WE definitely need this one too;
"Ergot Peptide Alkaloid Spectra of Claviceps-Infected Tall
Fescue, Wheat, and Barley" by James K. Porter, Charles W. Bacon, Ronald D.
Plattner, and Richard F. Arrendale. J. Agric. Food Chem. 1987 (35) 359-361.

(Rhodium: "Claviceps-Infected Tall Fescue/Wheat/Barley", Tryptamine Chemistry)CA: 77:P156333n : describes a method used to get 9.75g pure lysergamides from a 10 litre fermentation originally containing an estimated 15g.
*The Ergot Alkaloids; A. Stoll and A. Hofmann (THE);
Chapter 21, The Alkaloids, Manske (ed. ?) vol. VIII, pgs 725-779+.
Describes lots and lots and lots of chemical detail regarding
everything from biogenesis to complete chemical synthesis as a means
of confirming structure. Also has a section completely devoted to
"Derivatives of Ergot Alkaloids" in which the following processes
for synthesizing amides are discussed:
=> The azide process.
=> DMF-SO3 mixed anhydride method.
=> mixed Lysergic acid trifluoroacetic anhydride.
=> Lysergic acid chloride hydrochloride method.
=> N,N'- carbonyldiimidazole as condensing agent (Best IMHO).
there's also the Michael Valentine extraction, but I'd like to see some ref's before I go taking his word for it.
