    摘要:从容易获得的手性来源开始,已经合成了四种类型的手性胺.已发现这些手性胺与 L-脯氨酸结合是甲基乙烯基酮 (Mvk) 和芳香醛之间不对称 Morita-Baylis-Hillman (Mbh) 反应的有效助催化剂.相应的加合物以合理的化学产率和非常好的对映选择性(高达 83% Ee)形成.此外,与手性胺 4 和 L-脯氨酸的两种对映异构体的平行共催化反应表明,脯氨酸立体化学决定了新形成的手性中心的构型.此外,胺4A中游离羟基的存在提高了反应的对映选择性.基于这些发现,已经提出了这种助催化 Mbh 反应的合理机制.

    摘要:The present invention relates to novel Ruthenium catalysts and related borohydride complexes, and the use of such catalysts, inter alia, for (1) hydrogenation of amides (including polyamides) to alcohols and amines; (2) preparing amides from alcohols with amines (including the preparation of polyamides (e.g., polypeptides) by reacting dialcohols and diamines and/or by polymerization of amino alcohols); (3) hydrogenation of esters to alcohols (including hydrogenation of cyclic esters (lactones) or cyclic di-esters (di-lactones) or polyesters); (4) hydrogenation of organic carbonates (including polycarbonates) to alcohols and hydrogenation of carbamates (including polycarbamates) or urea derivatives to alcohols and amines; (5) dehydrogenative coupling of alcohols to esters; (6) hydrogenation of secondary alcohols to ketones; (7) amidation of esters (i.e., synthesis of amides from esters and amines); (8) acylation of alcohols using esters; (9) coupling of alcohols with water to form carboxylic acids; and (10) dehydrogenation of beta-amino alcohols to form pyrazines. The present invention further relates to the novel uses of certain pyridine Ruthenium catalysts.
