摘要

Under stannic chloride catalysis, 2-carbomethoxy-2-cyclohexen-1-one (5) was found to undergo Diels-Alder reaction with a variety of dienes to give directly the cis-1-octalone system possessing a functionalized substituent at the angular position. With unsymmetrically substituted dienes, the adducts were those predicted on the basis of the normal rules (ortho and para) governing the orientation of Diels-Alder addition. In cases where differing ...
