| Abstract: | C,N-diarylnitrones and C-amido-N-arylnitrones add diastereoselectively to the substituted arylpropenones to give the substituted isoxazolidine possessing 3RS,4SR,5SR configuration. Replacement of the aryl groups either in the position 3 of chalcone or at the nitrogen atom of nitrone by the methyl group decreased the rate of cycloaddition. |
