The asymmetric organocatalytic hydrogenation of benzoxazines, quinolines, quinoxalines and 3H-indoles in continuous-flow microreactors has been developed. Reaction monitoring was achieved by using an inline ReactIR flow cell, which allows fast and convenient optimization of reaction parameters. The reductions proceeded well, and the desired products were isolated in high yields and with excellent enantioselectivities.
已经开发了在连续流微反应器中对苯并噁嗪、喹啉、喹啉和3- H-吲哚的不对称有机催化氢化反应。通过使用内联ReactIR流动池进行反应监测,可以快速方便地优化反应参数。还原反应进行顺利,并且所需产物以高收率和优异的对映选择性分离。
