A simple and efficient procedure for synthesis of optically active 1,3,4-oxadiazole derivatives containing L-amino acid moieties
N-phetaloyl-L-amino acid 1,3,4-oxadiazole diacylhydrazide pyridoyl hydrazide
2010/10/19
Some new unsymmetrical and optically active 2,5-disubstituted 1,3,4-oxadiazoles 5a-j were efficiently synthesized by cyclization reaction of diacylhydrazides 4a-j. The synthesis of the title compounds...
