Abstract

A synthetic strategy involving a Z-selective Horner-Wadsworth-Emmons olefination was developed for the preparation of the sarcoglaucolone precursor methyl (2Z,6E)-8-(methoxymeth­oxy)-6-methyl-2-[(3E)-4-methyl-5-oxopent-3-enyl]-9-[(trimethylsilyl)methyl]deca-2,6,9-trienoate. The target compound was isolated in a E/Z ratio of 17:83
