1,5-Induction in reactions between 4-aminoallylstannanes and aldehydes promoted by Lewis acids
Abstract
Transmetallation of tributyl[(4S, 2E)-4-dibenzylaminopent-2-enyl]stannane 7 by tin(IV) bromide generates an allyltin tribromide which reacts with aldehydes to give 5-aminohex-3-enols 8 with effective 1,5-asymmetric induction.
