A Synthetic Approach to Tetrasubstituted Alkenes: Using β‐Carbonyl Benzothiazol‐2‐yl Sulfones as Electrophiles.

A novel olefination method based on the modified Julia olefination reaction was developed. The reactions of -carbonyl benzothiazol-2-yl sulfones with a series of alkynyllithiums and TMSCN gave the corresponding -alkoxy sulfone intermediates, which underwe
