amphiphilic reactivity in the context of enantioselective catalysis are described. Commercially available π-allyliridium C,O-benzoates, which are stable to air, water and SiO2 chromatography, and are well-known to catalyze allyl acetate-mediated carbonyl allylation, are now shown to catalyze highly chemo-, regio- and enantioselective substitutions of branched allylic acetates bearing linear alkyl groups with
描述了对映选择性催化背景下两亲反应性的第一个例子。市售的 π-烯丙基 C,O-苯甲酸酯对空气、水和 SiO2 色谱稳定,众所周知可催化乙酸烯丙酯介导的羰基烯丙基化,现在显示可催化高度化学、区域和对映选择性取代带有直链烷基和伯胺的支链乙酸烯丙酯。
