Abstract
A series of some hydrazones derivatives (3-7) have been synthesized from the reaction of hydrazide (2) with substituted benzaldehyde. While oxazridine derivatives (8-12) were synthesized by oxidation with hydrazones derivatives (3-7) with m-chloro per benzoic acid, the of these compounds (8-12) with ammonium thiocyanate afforded compounds (13-17). While the reaction of compound (2) with indole-2,3-dione afforded compound (18) while in reaction with mercaptoacetic acid gave Spiro indoline-2,3-thizolidine derivatives (19) when the compound allowed to react with conc., sulfuric acid and phosphoric pent oxide afford (20) and (21) respectively.
