Binary heterocyclic systems containing the ethylideneamino linkage: synthesis of some new heterocyclic compounds bearing the naphtho-[2,1-b]furan moiety

Ethylidene hydrazine (4a,b) and thiazolidin-4-one (5) derivatives were synthesized by the reaction of ethylidenethiosemicarbazide derivative (3a) with α-haloketone/ethyl bromoacetate, respectively. Hetrocyclization of ethylideneacetohydrazide derivative (7) with o-phenolic aldehydes gave the corresp...
