  Asymmetric synthesis of a C1C19 fragment of ulapualide A

  摘要：

  The stereocontrolled synthesis of a C1-C19 fragment of ulapualide A has been accomplished. The C3 hydroxyl-bearing stereocenter was established by Jacobsen's hydrolytic kinetic resolution (HKR) of a terminal epoxide. while the C9 methyl stereocenter was introduced through an asymmetric crotylation using chiral organosilane (S)-7. Union of the C1-C6 and the C7-C19 fragments by a Kishi-Nozaki coupling, followed by oxidation and conjugate addition of hydride completed the preparation of the fragment.
