of tetrahydroimidazo[1,2‐a]pyridines by direct hydrogenation was achieved using a ruthenium/N‐heterocyclic carbene (NHC) catalyst. The reaction forgoes the need for protecting or activating groups, proceeds with complete regioselectivity, good to excellent yields, enantiomeric ratios of up to 98:2, and tolerates a broad range of functional groups. 5,6,7,8‐Tetrahydroimidazo[1,2‐a]pyridines, which are
使用钌/ N-杂环卡宾(NHC)催化剂,通过直接氢化完成对四氢咪唑并[1,2- a ]吡啶的对映选择性合成。该反应放弃了对保护基团或活化基团的需要,以完全的区域选择性,良好至优异的产率,高达98:2的对映体比例进行,并且耐受宽泛的官能团。5,6,7,8-四氢咪唑并[1,2一]吡啶,其在许多生物活性分子中发现,直接通过该方法获得的,其适用性是由几个功能性分子的(正式)合成证明。
