lipase-catalysed enantioselective synthesis of cyanohydrin esters was investigated, and the problem of previously reported low yields due to residual water in the reaction mixture was addressed. When the lipase was immobilised on Celite R-633 as a carrier, both the enantioselectivity and the reaction times for this dynamic kinetic resolution were improved, thus enabling a highly enantioselective synthesis of aromatic
对氰醇酯的碱和脂肪酶催化的对映选择性合成进行了研究,并解决了先前报道的由于反应混合物中残留水而导致收率低的问题。当将脂肪酶固定在Celite R-633上作为载体时,该动态动力学拆分的对映选择性和反应时间均得到改善,因此可以高度对映选择性合成芳族和杂芳族氰醇乙酸酯。
