The preparation of t-butyl 4-diethylphosphono-3-oxobutanethioate (1) and Wadsworth- Emmons reaction with aldehydes and ketones is reported. Some of the products of these reactions were converted to unsaturated 3-oxomacrolides or 3-oxodiolides by transesterification in the presence of copper-(I)-trifluoroacetate.
