Synthesis of carboxylated pyrrolidine derivatives via 1,3-dipolar cycloadditions of homochiral double-stabilised E-azomethine ylids
摘要:
The preparation and subsequent diastereoselective 1,3- dipolar cycloaddition of E-carboethoxy-substituted azomethine ylids derived by condensing 5-(S)-phenylmorpholinone (1) with ethyl glyoxalate is described. Removal of the chiral template furnishes enantiomerically pure pyrrolidine-2,5-dicarboxylate derivatives.
