Abstract

AbstractThe reaction rate and stereoselectivity of intermolecular dipolar 1,3 cycloaddition of the C,N‐dialkylnitrone to olefins with hydroxyl groups and their derivatives were found to depend upon the type of hydroxyl group. The rate is accelerated in the order: magnesium alkoxide (OMgBr); free hydroxyl group (OH); ether (OR). Selectivities are improved moderately when magnesium alkoxide is used.
