  Synthesis of tetrahydrolipstatin

  摘要：

  An asymmetric synthesis of tetrahydrolipstatin (4) is described. Application of our previously described in situ cyclopentadiene alkylation-asymmetric hydroboration protocol provided the key chiral alcohol 9. In the course of this work, the presence of a free hydroxyl group was found to exert a strong directing effect on the regioselectivity of a Baeyer-Villiger reaction (16 --> 17). Subsequent transformations of lactone 17 produced tetrahydrolipstatin (4).
