α,β-unsaturated ones are performed in propionitrile (solvent) by the use of a catalytic amount of chiral tin(II) Lewis acid consisting of tin(II) triflate and a chiral diamine. The asymmetric environments created by the chiral catalysts in the enantioselective aldol reaction are discussed by employing five kinds of chiral diamines.
甲硅烷基烯醇醚与醛类(包括芳族,脂肪族和α,β-不饱和醛)的高度非对映和对映选择性的醛醇型反应,是通过使用催化量的手性锡(II)路易斯酸在丙腈(溶剂)中进行的。由三氟甲磺酸锡(II)和手性二胺组成。通过使用五种手性二胺,讨论了手性催化剂在对映选择性羟醛反应中产生的不对称环境。
