摘要：

All under control! A catalytic asymmetric 1,3-dipolar cycloaddition reaction of nitrones to alkylidene malonates, catalyzed by chiral N,N'-dioxide-Ni(ClO4)2.6 H2O complexes, has been developed with excellent yields, diastereo-, and enantioselectivities (see scheme, R1=aryl, R2=alkyl, R3, R 4=Ph). In addition, a possible transition state has also been proposed to elucidate the high level of enantio- and diastereocontrol. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
