Abstract
In this paper, enantioselective formation of E/Z-4,5- dihydro spiro[3- phenyl-5-substituted phenyl isoxazole-4,4'- (2',4'-dihydro-2',5'-disubstituted-3'H-pyrazol-3'-ones)] is described by means of stereospecific 1,3-dipolar cycloaddition of benzonitrile oxide with 4-arylmethylene-2,4-dihydro-2,5- disubstituted-3H-pyrazol -3-ones.
