标题:硫(iv)介导的不对称杂环交叉偶联.
摘要:尽管金属介导的交叉偶联在现代有机化学中具有巨大的用途,但涉及含氮杂芳烃的偶联反应仍是一项艰巨的任务-将路易斯碱性原子配入金属中心通常需要提高温度,增加催化剂负载等.在此,我们报道了硫(iv)介导的交叉偶联可修正,以有效合成杂芳族底物.将杂芳基亲核试剂加至简单的,易于获得的烷基亚磺酰基(iv)氯化物中,可以形成三角双金字塔型硫烷中间体.由此的还原消除以实用和有效的方式提供了双杂芳基产物.

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.
