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.
A synthetic method to prepare azulen-1-yl ketones was developed via oxidative cleavage of the C-C double bond in the reaction of easily obtainable N-sulfonyl enamides with Cs2CO3 under air and natural sunlight and in the absence of a photosensitizer. Oxidative cleavage of C-C triple bonds was also demonstrated for the synthesis of azulen-1-yl ketones via a(More)
