  Short asymmetric synthesis of (S,S)-PDP using l-prolinol derivative as economic starting material

  摘要：

  (S,S)-PDP (5d) and its backbone (2S2'S)-bipyrioldine (1) have been extensively applied as the scaffold of various chiral ligands in catalytic asymmetric syntheses In this study, new short asymmetric syntheses of these two important C-2-symmetrical nitrogen heterocycles have been accomplished employing economically available t-prolinol derivative 10 as the starting material Excellent diastereoselectivity was achieved of the key Grignard addition to imine intermediate utilizing (S)-N-tert-butanesulfinamide as the chiral auxiliary (C) 2010 Elsevier Ltd All rights reserved
