Palladium(II)-catalysed asymmetric acetalization of alkenes
Abstract
Methacrylamide bearing 4-tert-butyloxazolidin-2-one as a chiral auxiliary reacts with methanol in the presence of PdCl2 catalyst to give the corresponding acetal in 95% diastereoisomeric excess, and removal of the auxiliary results in the formation of chiral acetals.
