  Enantioselective total synthesis of (−)-denticulatins A and B using a novel group-selective aldolization of a meso dialdehyde as a key step

  摘要：

  The diastereoselective synthesis of (-)-denticulatin A (1a) was achieved for the first time in 9 steps (41% yield) based on a novel group-selective aldolization of a meso dialdehyde as a key step. The inherent chirality present in bornanesultam 4 was thus transmitted to the five stereocenters spanning C-4-C-8 in key intermediate 8. In addition, denticulatin B (1b) was obtained from the common intermediate 8 en route to denticulatin A in 10 steps and 35% overall yield. (C) 1997 Elsevier Science Ltd.
