Synthesis of some azetidonone and 1, 3-oxazepine deritives from thymol

الملخص EN

A series of some azetidines -2-one derivative (11-16) have been synthesized by cyclocondensation of various hydrazones derivatives (3- 10) with chloroacetyl chloride in the presence of triethylamine.

Hydrazones (3-10) were synthesized from the reaction of hydrazide (2) with various substituted benzaldehyde.

Oxazepain 4,7-dion derivatives (17-22) were synthesized from the reaction of hydrazones derivatives (3- 10) with maleic anhydride
