Mphahlele, MJ
"Molecular Iodine -- An Expedient Reagent for Oxidative Aromatization Reactions of alpha,beta-Unsaturated Cyclic Compounds."
Molecules 2009, 14(12):5308-5322

Abstract
Prompted by the scant attention paid by published literature reviews to the applications of molecular iodine in oxidative aromatization reactions, we decided to review methods developed to-date involving iodine as an oxidant to promote aromatization of a,b-unsaturated cyclic compounds.

The article lso contains a short review of other methods. - Enkidu

Arylethylamine psychotropic recreational drugs: a chemical perspective
Sally Freeman a,*, John F. Alder
Eur. J. Med. Chem.
2002, 37,  527–539


Abstract
The arylethylamines substituted in the aryl ring, side-chain carbons and on the terminal amine, comprise a large number of human mood and behaviour altering chemicals. Some of these psychotropic drugs have been used since pre-history, but in many states are proscribed and are consequently subject to clandestine synthesis and illegal traffic world-wide in the forms particularly of amphetamines and to a lesser extent tryptamines. The chemistry employed in the synthesis of these compounds is dictated often by the available precursors and relies usually on relatively simple, unsophisticated conversion reactions to a suitable product. The internet web sites and documentation of the recreational drug culture have been studied alongside the professional scientific and regulatory literature. The review demonstrates the great complexity of the chemistry and neuro-pharmacology of these chemicals and the challenge faced by legislative bodies to control their traffic and use for the sake of social welfare.

Synthesis and Pharmacological Examination of Benzofuran, Indan, and Tetralin
Analogues of 3,4-( Methy1enedioxy)amphetamine
Aaron P. Monte, Danuta Marona-Lewicka, Nicholas V.Cozzi, and David E. Nichols
J. Med. Chem.
1993,36,3700-3706


Abstract
Benzofuran,indanandtetrahydronaphthalene analogsof3,4-(methy1enedioxy)amphetamine(MDA) were prepared in order to examine the role of the dioxolering oxygenatoms of MDA ininteracting with the serotonin and catecholamine uptake carriers. The series of compounds was evaluated for discriminative stimulus effects in rats trained to discriminate saline from the training drugs (S)-(+)-MBDB(IC),MMAI(3),and(S)-(+)-amphetamine and for the ability to inhibit the uptake of [3H]serotonin, [3H]dopamine, and [3Hlnorepinephrine into crude synaptosome preparations.

Behaviorally,thebenzofuran and indan analogs4-6 produced similar discriminative cues,whereas the tetralin derivative 7 did not fully substitute for the training drugs. The results in the invitro pharmacology studies indicate that selectivity for 5-HTversus catecholamine uptake carriers may be modulated by the position and orientation of ring oxygen atoms. However,the non oxygenated is ostere 6 possessed high potency at all uptake sites examined. Enlargement of the saturated ring by one methylene unit to give the tetralin derivative resulted in a large (3-4-fold) reduction in activity at catecholamine sites.

Information acquired from Blacklight .....one should know




Recreational ketamine: from pleasure to pain
Dan Wood, Angela Cottrell, Simon C. Baker, Jennifer Southgate, Maya Harris, Simon Fulford, Christopher Woodhouse, David Gillatt
BJU International
2011, 107(12), pp.1881–1884
DOI: 10.1111/j.1464-410X.2010.10031.x
PMID: 21314885


Abstract
Ketamine has become increasingly recognized as a drug of recreational use. Individuals using significant amounts have developed symptoms including a small painful bladder, ureteric obstruction, papillary necrosis and hepatic dysfunction. The present paper examines the current literature on the relationship between ketamine use and these symptoms. Our own clinical experience and the data available clarify the causal relationship, and further data help to elucidate the mechanism of damage. On the basis of continued work and development with patients who are ketamine users we suggest an assessment and treatment regime that includes cessation of ketamine use and adequate analgesia to overcome symptoms. In conclusion, it is important for medical practitioners who encounter patients with these symptoms to ask about recreational drug use. Ketamine remains a safe and effective drug to use under appropriate medical supervision. Patients identified as suffering from this syndrome will need to be referred to a urological unit with an interest in the treatment of the condition.

Metabolism and toxicological analyses of hallucinogenic tryptamine analogues being abused in Japan
Tooru Kamata · Munehiro Katagi Hitoshi Tsuchihashi
Forensic Toxicol
2010,  28:1–8
DOI 10.1007/s11419-009-0087-9


Abstract
 Hallucinogenic tryptamine analogues, an important class of drugs of abuse, can be naturally occurring or chemically synthesized compounds. In Japan, psilocin and psilocybin (ingredients of “magic mushrooms”) and 5-methoxy-N,N-diisopropyltrypt- amine (5-MeO-DIPT; a synthetic tryptamine) seem to be particularly problematic due to their extensive abuse. This review is focused on human metabolism and foren- sic toxicological analyses of the above three tryptamine analogues.

In humans, psilocybin is rapidly dephosphor- ylated to form psilocin, and most of the psilocin is even- tually conjugated to form its glucuronide. On the other hand, 5-MeO-DIPT is mainly metabolized via O-demeth- ylation, 6-hydroxylation, and N-deisopropylation, partly followed by conjugation to form their sulfates and glucuronides. Suitable hydrolysis should be, therefore, applied for sensitive and effective analysis of the metabo- lites.

In analyzing psilocin and psilocybin by gas chro- matography-mass spectrometry (GC-MS), derivatization is necessary for their discriminative identification. Although 5-MeO-DIPT and its three major metabolites can be analyzed by GC-MS without any derivatization, trimethylsilyl derivatization provides improvement of their peak shapes and intensities. In contrast to GC-MS, liquid chromatography-mass spectrometry and liquid chromatography-tandem mass spectrometry allow us not only to discriminate psilocin and psilocybin without derivatization, but also to directly analyze their conju- gated metabolites.

Copper-Catalyzed Oxidative Amidation of Aldehydes with Amine Salts: Synthesis of Primary, Secondary, and Tertiary Amides
Subhash Chandra Ghosh, Joyce S. Y. Ngiam, Abdul M. Seayad, Dang Thanh Tuan, Christina L. L. Chai, and Anqi Chen
Journal of Organic Chemistry
2012, 77 (18), pp 8007–8015
DOI: 10.1021/jo301252c

Abstract
A practical method for the amidation of aldehydes with economic ammonium chloride or amine hydrochloride salts has been developed for the synthesis of a wide variety of amides by using inexpensive copper sulfate or copper(I) oxide as a catalyst and aqueous tert-butyl hydroperoxide as an oxidant. This amidation reaction is operationally straightforward and provides primary, secondary, and tertiary amides in good to excellent yields for most cases utilizing inexpensive and readily available reagents under mild conditions. In situ formation of amine salts from free amines extends the substrate scope of the reaction. Chiral amides are also synthesized from their corresponding chiral amines without detectable racemization. The practicality of this amide formation reaction has been demonstrated in an efficient synthesis of the antiarrhythmic drug N-acetylprocainamide.

Bromine Derivitives of Cyanuric Acid
John A. Wojtowicz
The Chemistry and Treatment of Swimming Pool and Spa Water
2004,Volume 5, Number 2, pages 16–19


Abstract
Various bromine derivatives of cyanuric acid have been prepared and characterized. These
include: partially and fully brominated derivatives of di- and trichloroisocyanuric acids, and
sodium dichloroisocyanurate. In addition, partially brominated derivatives of the double salts of
trichloroisocyanuric acid and potassium dichloroisocyanurate are possible. The bromine
derivatives have lower solubilities than the chlorinated analogs. None of these compounds have
been commercially developed.
