β-substituted (E)-crotylsilanes (R)-7 and (S)-8, bearing an alkyl or aryl group adjacent to the stereogenic C-Si center have been synthesized in an efficient four-step procedure initiated with a regio- and stereoselective silylformylation of a terminal alkyne catalyzed by dirhodium(II) perfluorobutyrate.
已通过有效的四步法合成了功能化的β-取代的(E)-巴豆基硅烷(R)-7和(S)-8,它们带有与立构C-Si中心相邻的烷基或芳基,并通过区域四氢键引发和由全氟丁酸二铑(II)催化的末端炔烃的立体选择性甲硅烷基甲酰化。
