Abstract
Abstract Hydroxyl groups on an unsaturated imine, which may be readily obtained from the corresponding unsaturated aldehyde and the 1,2-ethanolamine derivative, were found to efficiently activate a [4+4] dimerization reaction to produce the eight-membered 1,5-diazacyclooctane. A novel OH–π interaction between the two imines, in addition to the stabilization of the eight-membered diacetals, was proposed based on density functional theory calculations.
