The [2,3]-Wittig variant of (Z)-crotyl ether involving trimethylsilylethynyl (or 1-propynyl) group as the key substituent on the carbanion terminus exhibits an exceptionally high level of erythro-selection, and its synthetic potential is illustrated in the formal synthesis of antibiotic (±)-oudemansin.
