Highly endo-diastereoselective 1,3-dipolarcycloadditions between acrylates derived from methyl (R)- and (S)-lactate, as chiral dipolarophiles, and azomethineylides derived from glycine and α-substituted amino acids are described. The origins of the observed excellent stereocontrol are interpreted on the basis of computational studies on model systems. This methodology was successfully employed for

HTS of the compound collection for inhibition of the HCV RNA dependent RNA polymerase identified two 168 member N-acyl pyrrolidine combinatorial mixture hits. Deconvolution and expansion of these mixtures by solid phase synthesis to establish initial SAR and identify a potent inhibitor is reported. (c) 2005 Elsevier Ltd. All rights reserved.
