A new strategy for the synthesis of N-alkoxycarbonyl aryl α-imino esters in the presence of dirhodium tetraacetate [Rh2(OAc)4] is reported to produce the desired compounds in high yield (up to 96%) under mild reaction conditions. The application of the synthetic method is demonstrated in enantioselective reduction and Friedel–Crafts reaction of indoles to afford the corresponding chiral arylglycines
据报道,在四乙酸二ho酯[Rh 2(OAc)4 ]存在下合成N-烷氧基羰基芳基α-亚氨基酯的新策略可以在温和的反应条件下以高收率(最高达96%)产生所需的化合物。合成方法的应用在吲哚的对映选择性还原和Friedel-Crafts反应中得到了证明,分别以高收率和优异的ee提供了相应的手性芳基甘氨酸和吲哚衍生物。
