Enantioselective divergent approaches to (−)-platencin and (−)-platensimycin have been developed. A rationally designed chiral synthetic intermediate, possessing a useful α,β-unsaturated sulfone functionality, which served as a masked ketone as well as a good Michael acceptor, was successfully prepared via the highly enantioselective catalytic asymmetric intramolecular cyclopropanation (CAIMCP) developed
已经开发了对-(-)-盘菌素和(-)-盘菌素的对映选择性发散方法。通过在我们实验室开发的高度对映选择性催化不对称分子内环丙烷化(CAIMCP)成功地制备了合理设计的手性合成中间体,该中间体具有有用的α,β-不饱和砜官能团,可作为掩蔽的酮以及良好的迈克尔受体。 。
