title: Diastereoselective N-sulfonylaminoalkenylation of azulenes from terminal alkynes and azides via N-sulfonyl-1,2,3-triazoles.
abstract: The development of rhodium-catalyzed diastereoselective N-sulfonylaminoalkenylation of azulenes using N-sulfonyltriazoles is described. This procedure can be successfully applied to rhodium-catalyzed diastereoselective N-sulfonylaminoalkenylation of azulenes starting from terminal alkynes and N-sulfonylazides via a three-component semi-one-pot process.
