Anti-carbometalation of alkynyl sulfides using indium tribromide and ketene silyl acetals

We developed the regioselective anti-carbometalation of alkynyl sulfides via the use of InBr3 and organosilicon nucleophiles to give β-mercaptoalkenylindium compounds. The structure of β-mercaptoalkenylindium was characterized by X-ray crystallographic analysis. A variety of disubstituted alkenyl sulfides were regio- and stereoselectively obtained by either halogenation or Pd-catalyzed cross-coupling with aryl halides using the mercaptoalkenylindiums.

Electrotelluration: A new approach to tri- and tetrasubstituted alkenes

A novel electrotelluration process is described in which a Michael addition of an alkyl or aryl tellurolate anion occurs onto an activated alkyne with subsequent trapping of a vinyl anion with electrophiles (aldehydes and ketones) other than a proton. This process provides an efficient regio-and stereospecific route to tri- and tetrasubstituted alkenes. Methodologically significant examples of this chemistry were studied in which aryl and alkyl tellurolate anions were added to ω-keto alkynyl esters in a Michael reaction, and the incipient vinyl anions were trapped intramolecularly by the internal aldehydes. The reactive centers were tethered by different lengths of alkyl chains to form highly functionalized five-, six-, seven-, and eight-membered rings in modest to good yields.
