我们报告了我们在开发以 3-烷基羟吲哚作为亲核试剂的 Mo 催化的不对称烯丙基烷基化反应方面所做的工作。就羟吲哚亲核试剂的范围而言,该反应与 Pd 催化反应互补。许多3-烷基羟吲哚在温和条件下成功烷基化,得到具有优异收率和良好对映选择性的产品。据报道,该方法应用于制备二氢吲哚生物碱,如 (-)-毒扁豆碱、ent- (-)-去溴氟曲明 B 和 communesin B 的吲哚啉喹啉环。

The present invention relates generally to pharmaceutical agents containing a heterocyclic moiety, and in particular, to heterocyclic metalloprotease inhibiting compounds. More particularly, the present invention provides a new class of heterocyclic MMP-13 inhibiting compounds with a modified benzoxazine moiety, that exhibit an increased potency and selectivity in relation to currently known MMP-13 inhibitors.

The first example of Mo-catalyzed asymmetric allylation for the generation of quaternary stereocenters at a prochiral nucleophile is reported. A variety of 3-alkyl oxindoles can be alkylated with high yields and enantioselectivity. This method provides expedited access to (-)-physostigmine and its analogues.
报道了第一个在前手性亲核试剂上产生四元立体中心的 Mo 催化不对称烯丙基化的例子。多种 3-烷基羟吲哚可以以高产率和对映选择性进行烷基化。该方法提供了对 (-)-毒扁豆碱及其类似物的快速访问。
