Abstract

AbstractFour different (R)‐3‐substituted cyclohexanones of 65–96% enantiomeric purity have been prepared in 58–84% yields via organometallic conjugate additions to (S)‐2‐(p‐tolylsulfinyl)cyclohexenone in 2,5‐dimethyltetrahydrofuran (DMTHF) as a solvent which allows more effective metal ion chelation by the bidentate β‐ketosulfoxide (and therefore higher asymmetric induction) than does THF. Several recently‐reported organotitanium reagents have been used effectively for the first time as Michael donors.
