of the synthesis of the DEFG ring system of cneorin C 1, we were faced with the task of preparing the furyl substituted allyl alcohol 5 enantioselectively. Several different methods starting from enantioselective zinc-mediated alkylations were attempted, but none of them proved entirely satisfactory. The solution turned out to be enzymatic kinetic resolution through a highly enantioselective (E>300)
在合成神经胶蛋白C 1的DEFG环系统的过程中,我们面临着对映选择性制备呋喃基取代的烯丙醇5的任务。从对映选择性锌介导的烷基化反应开始尝试了几种不同的方法,但没有一种方法完全令人满意。结果证明该溶液在南极假丝酵母脂肪酶A的存在下通过高度对映选择性(E > 300)的酰化作用实现了酶促动力学拆分。
