The chiral N-heterocyclic carbene precursor 2, derived from L-pyroglutamic acid, was found to be an efficient precatalyst for the enantioselective esterification of alkylarylketenes with benzhydrol to give the corresponding esters in good yields with good to high enantioselectivities (up to 95% ee).
衍生自的手性N-杂环卡宾前体2L-焦谷氨酸被认为是烷基芳基烯酮与对映体的对映选择性酯化的有效催化剂。 苯氢 以高产率得到具有良好至高对映选择性(高达95%ee)的相应酯。
