A new, convenient route to the biologically active 2-(3-arylisoxazol-5-yl)benzoates 4 is reported.This route consists of 1,3-dipolar cycloaddition of aromatic nitrile oxides to 3-methylenephthalide to form the novel 3'-arylspiro-3-ones 3 and subsequent high-yield conversions of 3 to 4.

Cycloaddition of aromatic nitrile oxides to methyl o-vinylbenzoate produced methyl 2-(3-aryl-2-isoxazolin-5-yl)benzoates; the isoxazolines were converted to methyl 2-(3-arylisoxazol-5-yl)benzoates.Reaction of the nitrile oxide from o-methoxycarbonylbenzohydroximinoyl chloride (11) with phenylacetylene, styrenes, and aromatic nitriles resulted in methyl 2-(5-phenylisoxazol-3-yl)benzoate, methyl 2-(5-aryl-2-isoxazolin-3-yl)benzoates (15) and methyl 2-(5-aryl-1,2,4-oxadiazol-3-yl)benzoates, respectively.The isoxazolines 15 were converted to the corresponding isoxazoles 16.
