The successful example of chiral formamides that function as asymmetric catalysts is described. (S,S)-N,N-Bis(α-methylbenzyl)formamide mediates the enantioselective addition of allyl- and crotyltrichlorosilanes to aliphatic aldehydes with the assistance of hexamethylphosphoramide (HMPA) to afford the corresponding homoallylic alcohols in up to 98% enantiomeric excess.
描述了用作不对称催化剂的手性甲酰胺的成功实例。(S,S)-N,N-双(α-甲基苄基)甲酰胺在六甲基磷酰胺(HMPA)的协助下,将烯丙基三甲基和巴豆基三氯硅烷对映选择性加成到脂肪族醛中,从而提供相应的均烯丙基醇,对映体过量高达98% 。
