Abstract: In the presence of boron trifluoride, a variety of alkynyl sulfides and alkynyl sulfoxides undergo tandem cross-coupling/[3,3]-sulfonium rearrangement followed by 5-exo-dig heterocyclization. The strategy provides concise access to novel tetrasubstituted furans in good to high… read more here.

DOI: 10.1246/cl.200400
Abstract: 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-mercaptoal... read more here.
