Abstract: Sulindac sulfone is a metabolite of sulindac, a non-steroidal anti-inflammatory drug (NSAID), without anti-inflammatory ability. However, sulindac sulfone has been reported to significantly reduce polyps in patients with colorectal adenomatous polyposis in clinical trials. Thus,… read more here.

Abstract: Abstract Reaction of an 2-amino-2-ethynylmalonate derivative with an ethynyl sulfone allowed metal-free divergent synthesis of 1,6-dihydropyridines (DHPs) and 3,5-disubstituted pyrroles in one-pot. This facile atom-economical domino process involves hetero-conjugate addition and subsequent propargyl aza-Claisen-type rearrangement,… read more here.
