ENAMINONES IN ORGANIC SYNTHESIS: A NOVEL SYNTHESIS OF 1,3,5-TRISUBSTITUTED BENZENE DERIVATIVES AND OF 2-SUBSTITUTED-5-AROYLPYRIDINES
摘要:
Enaminones undergo self-condensation on reflux in acidic media yielding 1,3,5-trisubstituted benzene in very high yields. Reaction of enaminones 1a,b with ethyl propiolate affords 5-aroyl-1,3 -benzene dicarboxylate derivatives.
