摘要
Detailed experimental procedures are given for the preparation of the stereoisomeric (E)‐ and (Z)‐methyl‐α‐hydroxy and α‐methoxyimino‐4‐nitro‐1H‐imidazole‐1‐acetates and of the related acids. (Z)‐Isomers have been prepared by synthesis. (E)‐Isomers have been obtained only by photoisomerization. Decarboxylation of the acids left the corresponding aldehydes which are ideal compounds for structural studies and configurational assignments. Copyright © 1979 Journal of Heterocyclic Chemistry
