  Functional group hybrids. Reactivity of .alpha.'-nucleofuge .alpha.,.beta.-unsaturated ketones. 1. Reactions with organocopper reagents

  摘要：

  A series of alpha-nucleofuge alpha',beta'-unsaturated ketones encompassing a variety of structural types and nucleofuges was prepared. Treatment of these compounds with lithium dimethylcuprate or methylcopper leads primarily to either reductive cleavage of the alpha-nucleofuge or conjugate addition. Good alpha-nucleofuges favored the reduction pathway while poorer nucleofuges favored conjugate addition.

  日期：2004.11.1

  A practical and environmentally friendly method for oxidative rearrangement of five- and six-membered cyclic tertiary allylic alcohols to beta-disubstituted alpha,beta-unsaturated ketones by the IBX/DMSO reagent system is described. Several conventional protecting groups (e.g., Ac, MOM, and TBDPS) are compatible under the reaction conditions prescribed.

  描述了一种实用且环境友好的方法，该方法通过IBX / DMSO试剂系统将五元和六元环状叔烯丙基醇氧化重排为β-二取代的α，β-不饱和酮。在规定的反应条件下，几种常规的保护基团（例如Ac，MOM和TBDPS）是相容的。

  TiCl4-promoted aldol reaction of ketones as aldol acceptors followed by elimination of the titanoxy group from the Ti-aldolates affords β,β-disubstituted α,β-unsaturated carbonyl compounds in a one-pot procedure. The use of additives, such as DMF, N,N,N′,N′-tetramethylethylenediamine, and pyridine, in the elimination step was found to be important.

  TiCl 4促进的酮作为醛醇受体的醛醇缩醛反应，然后从Ti-醛醇酸酯中消除钛氧基，可以一锅法制得β，β-二取代的α，β-不饱和羰基化合物。发现在消除步骤中使用添加剂，例如DMF，N，N，N '，N'-四甲基乙二胺和吡啶是重要的。
