  Short Synthesis of (+)-Aspicilin via Asymmetric Hexahydroxylation of a Triene

  摘要：

  Asymmetric synthesis of the 18-membered lichen macrolide (+)-aspicilin has been achieved in 14 steps and 11% overall yield, starting from an achiral hydrocarbon, (3E)-hexadeca-1,3,15-triene. All four stereogenic carbinol centers have been introduced by three Sharpless asymmetric dihydroxylation (AD) reactions, using both AD-mix-beta and AD-mix-alpha to produce the hexol with very high regio- and enantioselectivity (epimeric excess of 88% at position 2, 96% at positions 3 and 4, and 86% at position 15).
