investigating the scope and limitations of the sulfur ylide initiated thio-Claisen rearrangement developed in our laboratory, we have been able to efficiently synthesize highly functionalized pyrroloindoline ring systems. This functionality is present in a variety of natural and non-natural products and here we report our synthesis of the debrominated analog of dihydroflustramine C.
在研究我们实验室开发的硫叶立德引发的硫代-克莱森重排的范围和局限性时,我们已经能够有效地合成高度官能化的吡咯并二氢吲哚环系统。这种功能存在于各种天然和非天然产品中,在这里我们报告了我们合成的二氢氟虫胺 C 的脱溴类似物。

The Rh(II)-catalyzed coupling of chiral 2-thiopyranylindoles with vinyl diazoacetates results in the generation of indolines having quaternarysubstitution at C(3) in high diastereoselectivity.

We have examined the coupling reactions of 2-thioindoles with vinyl diazoacetates in the presence of Rh(11) catalysts. While attempted enantio- and/or diastereoselective couplings using chiral catalysts and/or chiral auxiliaries on the vinyl diazoacetate have been largely unsuccessful, substrates having resident chirality on fused thiopyrans gave thioindolines with moderate to high diastereoselectivities.
