Lewis-acid catalyzed reaction of allyltins with aldehydes at −78 °C provide homoallyl alcohols with high stereoselectivity; 2-alkenyltins in general provide erythro adducts preferentially with an erythro/threo ratio greater than 12/1, whereas only threo adducts can be obtained from E-cinnamyltins.
路易斯酸催化烯丙基锡与醛在 -78 °C 下的反应提供具有高立体选择性的高烯丙醇;2-烯基锡通常优先提供赤/苏比大于12/1的赤加合物,而从E-肉桂锡只能获得苏加加合物。
