  The preparation of a diverse array of enantiomerically pure 1- and 2-sulfinyl dienes has been achieved via Stille coupling of halovinyl sulfoxides and vinyl stannanes, hydrogenation of 1-sulfinyl-1-en-3-ynes, or vinylcupration of 1-sulfinyl alkynes. Formation of the corresponding sulfinyl diene iron(0) tricarbonyl complexes was accomplished by utilizing Fe(CO)(5)/NMO or (bda)Fe(CO)(3) as iron(0) tricarbonyl transfer reagents. Installation of the iron(0) tricarbonyl fragment was shown to be highly diastereoselective (10-16:1) for (R)-(1Z)-1-sulfinyl dienes, most likely as a result of allylic 1,3-strain. The synthesis of a 1-sulfinyl-1,3,8,10-tetraene is also described.

  Enantiomerically pure 1-sulfinyl-1-en-3-ynes are prepared from 2-halovinylsulfoxides via Sonogashira or Stille coupling procedures. The trans-enynyl sulfoxides may be hydrogenated to provide (1E, 3Z)-dienylsulfoxides.
• Synthesis of Enantiopure 2-Malonylvinyl Sulfoxides via Addition-Elimination Reactions of 2-Halo- and 2-(Mesyloxy)vinyl Sulfoxides

  Enantiomerically pure (E)-2-bromo- and (E)-2-iodovinyl sulfoxides 3a and 3b have been prepared in multigram quantities from (E)-1,2-bis(tri-n-butylstannyl)ethene; enantiomerically pure (E)-2-(mesyloxy) vinyl sulfoxide 3c has been synthesized by reaction of the enolate derived from condensation of 1-lithiomethyl p-tolyl sulfoxide and DMF with methanesulfonyl chloride. These compounds react with anions derived from diethyl alkylmalonates to produce enantiopure 2-malonylvinyl sulfoxides in good to excellent yields and with a high degree of stereoselectivity. The transformations proceed through an ''addition-rotation-elimination'' sequence, and the stereochemical results reinforce the concept that nucleophilic additions to vinyl sulfoxides are sterically controlled and occur predominately syn to the sulfinyl electron lone pair.
