IN the reduction of the nitroalcohol.... to get a Proper isomer to use in an DL-amiorex synth, Would it be best to use EtOH with 37%Formaldahyde and activated zinc to reduce the nitro group?
Is AN acid nescesary to complete the reduction?
IS an equimolar ammount of Formaldehyde used or a catalyctic ammount?
Then how would one get a halogen at the 4 position on the oxilone ring where the phenyl group is position 5, without halogenating the phenyl ring.
