摘要

Vinyl and diene derivatives of thiolactomycin have been prepared via Horner–Wadsworth– Emmons olefination from protected 5-formyl-3, 5-dimethylthiotetronic acid. Several 4- position protecting groups and a variety of phosphonates were evaluated, with MOM protection and β-ketophosphonates yielding the highest ratio of the desired product to deformylated product.
