Dioxole derivativesR 0170 High Enantio- and Diastereoselective Induction of BINOL- and TADDOL-Modi-

fied Vinyloxy Ethoxides in C—C Coupling Reactions with Aldehydes. — The pro-cess affords β-hydroxy-1,3-dioxolanes with enantiomeric ratios up to 99:1. The reac-tions with (R) or (S)-BINOL are higher in yields and induction as comparable systems modified by TADDOL. — (MAIER, P.; REDLICH*, H.; RICHTER, J.; Tetrahedron: Asymmetry 16 (2005) 23, 3848-3852; Org.-Chem.
