The carbonylative Suzuki cross-coupling reactions of boronic acids with aryl iodides catalyzed by Pd 2 (dba) 3 as a ligand-free catalyst under atmospheric pressure of carbonmonoxide has been firstly developed. Under mild reaction conditions, a broad range of aryl/heteroaryl iodides and aryl/heteroaryl boronic acids were selectively coupled to afford the corresponding diaryl ketones in good to excellent

A systematic study of the asymmetric transfer hydrogenation (AH), using [arene/Ru(II)/TsDPEN] pre-catalysts, of a range of heterocyclic ketones is described. The products are formed in very high ee in cases where an ortho-substituted aromatic ring opposes the heterocycle on the ketone group. This provides a practical and selective access to a range of hetereocyclic alcohols in high ee, for the by ATH
描述了使用 [芳烃/Ru(II)/TsDPEN] 预催化剂对一系列杂环酮进行不对称转移氢化 (AH) 的系统研究。在邻位取代的芳环与酮基上的杂环相对的情况下,产物以非常高的 ee 形成。这为使用 Noyori-Ikariya 催化剂的 ATH 提供了实用和选择性地获得一系列高 ee 杂环醇。
