A silver(I)/ThioClickFerrophos complex catalyzed the endo selective asymmetric 1,3-dipolar cycloaddition reaction of methyl N-benzylideneglycinate (the source of azomethine ylides) with alpha,beta-unsaturated esters and maleimides to give the endo-2,4,5- and 2,3,4,5-substituted pyrrolidines in good yields with high enantioselectivities (up to 99% ee). The complex also effectively catalyzed the endo selective reactions with beta-nitrostyrene to give the 4-nitropyrrolidine in a high enantioselectivity. (C) 2010 Elsevier Ltd. All rights reserved.
