Abstract
The mild preparation of (E)-allylic acetals derived from N,N,N',N'-tet ramethyltartaramide is described. The desired chiral acetals are obtai ned by transacetalization of the corresponding acyclic acetals with a catalytic amount of pyridinium p-toluenesulfonate in DMF at room tempe rature.
