dataset
posted on 2012-04-20, 00:00 authored by Lin Hao, Yu Du, Hui Lv, Xingkuan Chen, Huishen Jiang, Yaling Shao, Yonggui Robin ChiThe first N-Heterocyclic Carbene (NHC) mediated activation of stable carboxylate esters to generate enolate intermediates is disclosed. The catalytically generated arylacetic ester enolates undergo enantioselective reactions with α,β-unsaturated imines.
