Since the Z isomer of chlorprothixene (1) is far more active than its E counterpart, it was of interest to develop a stereoselective synthesis for this class of compounds. Insertion of a benzenesulfonamido group at the peri position of a chlorprothixene precursor did affect the stereochemistry of side-chain olefin formation, but after hydrolysis attempted removal of the resulting amine led to a Widman-Stoermer
