Conjugate addition of thiophenol to γ-alkoxy-alkynone, 4, proceeds with up to 4:1 Z:E stereoselectivity.However, 2-mercaptobenzothiazole reacts to afford only the Z-isomeric vinyl sulfides.The Z-vinyl sulfides are readily converted to stereopure E-β-disubstituted enone, 8a, providing a convenient, practicable 2-step synthesis. 8a and 8b are also obtained via cuprate addition-equilibration, but with a Z:E ratio of View More
