BIS(TERT-BUTYLSULFONYL)ACETYLENE AS A GENERAL SYNTHETIC EQUIVALENT OF ALKYNES IN DIELS-ALDER CHEMISTRY. I: HIGHLY SELECTIVE REDUCTION AND ALKYLATING MONODESULFONYLATION OF Z-1,2-BIS(TERT-BUTYLSULFONYL)ETHENES

Bicyclic (Z)-1,2-Bis(tert-butylsulfonyl)ethenes arising from Diels-Alder reactions of bis(tert-butylsulfonyl)acetylene are efficiently reduced to monosulfones by samarium(II) iodide and alkylatively monodesulfonylated by organolithium compounds.
