Studies on the [2+3] cycloaddition reaction of nitrile oxides to abietic acid esters

Abstract

[2+3] Dipolar cycloadditions of aromatic nitrile oxides to abietic acid esters were investigated. The reactions showed complete site selectivity and regioselectivity, while the stereoselectivity depended on the structures of the dipolarophiles.
