  Total Synthesis of Dolabelide D

  摘要：

  The first total synthesis of dolabelide D (or of any of the closely related dolabelides) has been achieved with a longest linear sequence of 17 steps. Key features of the synthesis include an application of the catalytic asymmetric silane alcoholysis, the tandem silylformylation-crotylsilylation, and a Brook-like 1,4-carbon to oxygen silyl migration.

  [GRAPHICS]A synthesis of the C(15)-C(30) fragment of Dolabelides A and B has been achieved. The recently developed asymmetric silane alcoholysis and tandem silylformylation-crotylsilylation reactions were used as the key steps to establish the C(23)-C(27) 1,5-syn-diol. In addition, the flexibility of this methodology has been demonstrated with an efficient synthesis of the C(24)-C(25) trisubstituted olefin.
