[摘要]:An advanced intermediate vinyl iodide corresponding to the C1-C13 fragment of the macrolide biselyngbyaside was prepared by a cross-metathesis reaction between vinyl alcohol and alkene building blocks. The latter fragment, containing two stereocenters, was obtained by employing an asymmetric alkylation, a Wittig reaction, a hydrozirconation, and a Brown allylation as key steps. |
