An efficient procedure for the stereocontrolled construction of 2H‐thiopyrano[2,3‐b]quinoline scaffolds has been developed, starting from simple compounds. The domino Michael/aldol reactions between 2‐mercaptobenzaldehydes and enals, promoted by chiral diphenylprolinol TMS ether, proceed with excellent chemo‐ and enantioselectivity to give the corresponding synthetically useful and pharmaceutically
从简单的化合物开始,已经开发出了一种有效的立体控制2 H -thiopyrano [2,3-b]喹啉骨架的方法。手性二苯基脯氨醇TMS醚促进的2-巯基苯甲醛与烯醛之间的多米诺米歇尔/羟醛反应,具有出色的化学和对映选择性,可提供相应的合成上有用的和药学上有价值的2 H-硫代吡喃并[2,3-b]喹啉ee的产率为90–99%。
