An efficient, copper-catalyzed [3+1+1] cycloaddition reaction was developed for the expedient synthesis of pharmacologically interesting polysubstituted pyrroles from easily available nitrones and α-acidic isocyanides. The given approach features a new mo

Reaction of -aryl-N-phenyl nitrones with 3.methyl-1-phenyl-2-pyrazoline-5-one in the presence of a catalytic amount of silica tungstic acid in EtOH/H2O afforded, unexpectedly, high yields of bis(3-hydroxy-1-phenylpyrazolyl)-arylmethanes instead of the two possible 1,3-addition products. This is the first report of the synthesis of bis(3-hydroxy-1-phenylpyrazolyl)-arylmethanes via the reaction of nitrones and a pyrazolin-5-one. A possible mechanism for the process is suggested.

A series of novel 5-substituted isoxazolidine derivatives 3a(i-viii), 3b(i-viii) and 3c(i-viii) have been prepared and their antifungal activity on Aspergillus flavus, Fusarium moniliforme and Botrydiplodia theobromae have been evaluated.
