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.

The multicomponent condensation of various β-dicarbonyl compounds, acrolein and (S)-2-phenylglycinol was found to provide a one-pot access to chiral 6-carbonyl-3-phenyl-2,3,8,8a-tet-rahydro-7H-[l,3]oxazolo[3,2-a]pyridines. The value of this methodology is illustrated by the short and efficient synthesis of (-)-lupinine.
