of a chiral tin(II) Lewis acid, the silyl enol ether derived from (E)-phenyl α-t-butyldimethylsiloxyacetate reacted with aldehydes to afford the corresponding anti-aldol adducts, anti-α,β-dihydroxy ester derivatives, in high yields with high diastereo- and enantioselectivities.
在手性锡(II)路易斯酸的存在下,衍生自(E)-苯基α-叔丁基二甲基甲硅烷氧基乙酸酯的甲硅烷基烯醇醚与醛反应,得到相应的抗-醛醇加合物,抗-α,β-二羟基酯衍生物,具有高的非对映选择性和对映选择性。
