A reduction of quinolines to synthetically versatile tetrahydroquinoline molecules with I₂ and HBpin is described. In the presence of iodine (20 mol%) as a catalyst, reduction of quinolines and other N-heteroarenes proceeded readily with hydroboranes as the reducing reagents. The broad functional-group tolerance, good yields and mild reaction conditions imply high practical utility.

碘在温和的反应条件下催化还原喹啉†

描述了用I ₂和HBpin将喹啉还原为合成通用的四氢喹啉分子。在碘（20mol％）作为催化剂的存在下，以氢硼烷作为还原剂容易地进行喹啉和其他N-杂芳烃的还原。宽泛的官能团耐受性，良好的收率和温和的反应条件意味着较高的实用性。
