Catalytic asymmetricconstruction of the biologically important spiro[pyrrolidin‐3,2′‐oxindole] scaffold with contiguous quaternarystereogeniccenters in excellent stereoselectivities (up to >99:1 d.r., 98 % ee) has been established by using an organocatalytic 1,3‐dipolar cycloaddition of isatin‐based azomethine ylides. This protocol represents the first example of catalytic asymmetric 1,3‐dipolar

e-based spirooxindole has been developed via a chiral cinchona alkaloid catalyzed asymmetric three-component [3 + 3] cyclization of cyclic enaminone, isatin, and malononitrile, which afforded a series of tetrahydroquinolin-5-one-based spirooxindoles in high yields and with excellent enantioselectivities (up to 99% yield, 97:3 er). This reaction could be applicable to large-scale synthesis of enantioenriched

The first catalytic asymmetric isatin-involved Povarov reaction has been established. This method provides an unprecedented approach to access the enantioenriched spiro[indolin-3,2′-quinoline] scaffold with concomitant creation of two quaternary stereogenic centers in high yields and excellent stereoselectivities (all >99:1 dr's, up to 97% ee).
已经建立了第一个催化的不对称的由靛红参与的Isova Povarov反应。该方法提供了一种空前的方法来获得对映体富集的螺[吲哚-3,2'-喹啉]支架,并伴随以高收率和出色的立体选择性(全部> 99:1 dr 's,高达97%)创建了两个四级立体生成中心。ee)。
