by the reaction of acid chloride 3 with α-aracyl(β-2-furyl)acrylic acid hydrazides (2a-d) in a high yield, one pot reaction. On the other hand, 2-(2-chloroethyl)-5-[α-aracyl-β-(2-furyl)]-(E)-vinyl-1,3,4-oxadiazoles (7a-d) were also prepared by cyclodehydration of N1[α-aracyl-β-(2-furyl)acroyl-N2[3-chloro-propanoyl] hydrazine derivatives (4a-d). The proposed structures of the products were confirmed by
