The first asymmetric hydrogenation of 2,7-disubstituted 1,8-naphthyridines catalyzed by chiral cationic ruthenium diamine complexes has been developed. A wide range of 1,8-naphthyridine derivatives were effectively hydrogenated to give 1,2,3,4-tetrahydro-1,8-naphthyridines with up to 99% ee and full conversions. The method provides a practical and facile approach to the preparation of valuable chiral
已经开发了由手性阳离子钌二胺络合物催化的2,7-二取代的1,8-萘啶的不对称氢化。各种1,8-萘啶衍生物被有效地氢化,得到1,2,3,4-四氢-1,8-萘啶并具有高达99%的ee和完全转化率。该方法为制备有价值的手性杂环结构单元和用于新型P,N-配体的有用基序提供了一种实用且简便的方法。
