Convenient one-pot synthesis, anti-mycobacterial and anticancer activities of novel benzoxepinoisoxazolones and pyrazolones

Series of new benzoxepinoisoxazolones 4a-d and pyrazolones 6a-t were prepared by the cyclocondensation of substituted (E)-ethyl 3-oxo-2,3- dihydrobenzo[b]oxepine-4-carboxylates 3a-d with hydroxylamine hydrochloride and phenylhydrazine hydrochlorides 5a-k.

Facile synthesis of substituted ethyl 2-(chloromethyl)-2-hydroxy-2H-1- benzopyran-3-carboxylates

Ethyl 2-(chloromethyl)-2-hydroxy-2H-chromene-3-carboxylates 2a-2j have been synthesized by reaction of substituted salicylaldehydes with ethyl 4-chloro-3-oxobutanoate, in the presence of piperidine in CH2Cl 2 at room temperature, in good yields.
