Synthesis and anticancer activity of 3,5-diaryl-1,2,4-oxadiazole derivatives


Condensation of chlorobenzamidoxime with chloro­s ubstituted benzoyl chloride gave 3,5 Diaryl-1,2,4-oxa­diazole derivatives in a single step. These were screened for their anticancer activity.

Microwave assisted green synthesis of novel spiro isoxazolidine derivatives with α-chloro nitrones


Microwave assisted 1,3-dipolar cycloaddition reaction of α-chloro nitrones to novel α-N-methyl and α-N-phenylfuran derivative affords exclusively single regioselective 5-spiro isoxazolidines while the same reaction with α-methylene-γ-butyrolactone affords two diastereomeric 5-spiro isoxazolidines with high selectivity.
