  (−)-Lytophilippine A: Synthesis of a C1−C18 Building Block

  摘要：

  The convergent enantioselective synthesis of a protected C1-C18 building block for the total synthesis of (-)-lytophilippine A was achieved. A catalytic asymmetric Gosteli-Claisen rearrangement and an Evans aldol reaction served as key C/C-connecting transformations during the assembling of the C1-C7 subunit (10 steps from 4, 29%). The synthesis of the C8-C18 segment was achieved utilizing D-galactose as inexpensive ex-chiral-pool starting material (15 steps, 15%). The merger of the subunits was accomplished by a remarkably efficient sequence consisting of esterification and ring-closing metathesis (five steps, 56%).
