Tert-Butyl Nitrite Promoted Oxidative Intermolecular Sulfonamination of Alkynes to Synthesize Substituted Sulfonyl Pyrroles from the Alkynylamines and Sulfinic Acids

tert-Butyl nitrite promoted oxidative intermolecular sulfonamination of alkynes to synthesize substituted sulfonyl pyrroles from the alkynylamines and sulfinic acids via tandem addition/cyclization was developed. This reaction is performed well by employing tert-butyl nitrite as the oxidant, and various substituted sulfonyl pyrroles are formed in moderate to good yields with no requirement of metal catalysis.

A General, One-Pot Method for the Synthesis of Sulfinic Acids from Methyl Sulfones

A simple and efficient method for converting methyl sulfones to sulfinic acids is described. The process involves alkylation with a benzylic halide, followed by in situ elimination of the resulting styrene in the presence of excess base to yield a sulfinic acid in a single reaction process. The usefulness of the alkylation-elimination sequence is demonstrated by generating a variety of sulfinic acids from methyl sulfones. Late stage functionalization and 14C-labeling of several biologically active methyl sulfones were accessed via sulfinate intermediates.
