An Observation of Diastereoface Selectivity in Thermal Reactions Between δ-Alkoxyallylstannanes and Aldehydes.

Abstract The δ-alkoxyallylstannanes (4) and (5) react stereoselectively on heating with p -nitrobenzaldehyde to provide the homoallylic alcohols (14) - (17), with (14): (15) = 82: 18; (16): (17) = 73: 27.
