A highly diastereoselective Ugi reaction involving a chiral cyclic imine, two enantiomerically pure isocyanides and various carboxylic acids was employed for the synthesis of polyfunctionalized pyrrolidines. Both chiral substrates have been efficiently prepared by chemoenzymatic methodologies from readily available achiral substrates. This highly convergent approach can find an application in the fragment-based
涉及手性环状亚胺,两种对映体纯的异氰酸酯和各种羧酸的高度非对映选择性的Ugi反应用于合成多官能化吡咯烷。两种手性底物已经通过化学酶学方法从容易获得的非手性底物中有效地制备。这种高度收敛的方法可以在基于片段的药物发现过程中找到应用。
