  摘要：

  二氧代吡咯烷与各种简单烯烃的不对称催化逆电子需杂狄尔斯-阿尔德反应已经完成，显着扩展了这种环化对环状杂二烯和亲二烯体的适用性。一种新型铁盐强路易斯酸催化剂能够通过形成阳离子物种对二氧代吡咯烷进行 LUMO 活化，该方法产生了一系列双环二氢吡喃衍生物，具有优异的结果，包括高收率（高达 99%）、非对映选择性（高达99 : 1) 和在温和条件下的对映选择性（高达 99% ee）。这种简便的方案可用于几种生物活性分子的后期修饰以及转化为大环分子。基于对照实验阐明了对映选择性的起源。

  The invention concerns an aqueous dispersion of viscous silicone oils capable of being crosslinked into an elastomer by water elimination (condensation). The invention aims at obtaining an aqueous silicone dispersion corresponding to an optimal compromise in terms of adherence of the crosslinked elastomer on all types of supports, and the colloidal stability of the dispersion during preparation and storage. Said aqueous dispersion comprises a viscous silicone oil A, optionally a crosslinking agent B, optionally an adhesion promoter C (silane), a filler D, a catalyst E, an emulsifier F, optionally a functional additive G and water. Said dispersion is characterised in that the filler D is input into the process for obtaining the dispersion, in the form of an aqueous suspension of at least a hydrophilic compound (CaCO3SiO2, TiO2, Al2/H2O, organic polymer latex). The invention also concerns the preparation of said particularly stable dispersion since it has a residual emulsion rate T not less than 70%. The invention is useful for producing concentrated sealants and elastomer coating for insulating polymer foam (polyurethane).
