Abstract
A new method has been developed for the synthesis of acylhydrazines 5a-g by the reduction of unsymmetrical 1,3,4-oxadiazoles 4a-g by using sodium borohydride/acetic acid combination. Later on, acylhydrazines 5a-g were converted to their corresponding sulfonamide derivatives 6a-d.
Keywords: Acylhydrazine derivatives, benzenediazasulfonamide, 1,3,4-oxadiazole, sodium acytoxyborohydride
