“…Hetero-Michael reactions are efficient pathways that, historically, have been broadly used in synthesis, including several intramolecular examples to access a variety of heterocycles, namely, dioxolanes en route to 1,3-diols, 1 azacycles, 2 oxacycles, 3 thiacycles, 4 and bis-heterocycles. 5 Recently, double aza-Michael reactions have been utilized as efficient means to install two N–C bonds in a single operation. 6 Herein, we report a new approach termed ‘click, click, cy-click’ that utilizes two click reactions 7 and a double aza-Michael reaction for the facile synthesis of 1,2,5-thiadiazepane 1,1-dioxides.…”
