## Abstract The benzoylated Corey aldehyde 1a can be alkynylated with hept‐1‐ynyl‐triisopropoxytitanium in good chemical yield and high diastereoselectivity to the (R)‐alcohol 3c admixed with about 10% of the diastereomeric (S)‐alcohol 2c. Without removal of this admixture the (R)‐alcohol 3c was co

✦ Synopsis
Conjugate additions of enolate anions to a,B-unsaturated sulphoxides follcwed by sulphoxide-ketone transformations provided simple syntheses of cyclopentenones, and 2-phenylsulphinyloct-I-en-3-one provided a convenient electrophilic prostanoid B-side chain precursor.
