ChemInform Abstract: Unprecedented Synthesis of Aza‐Bridged Benzodioxepine Derivatives Through a Tandem Rh(II)‐Catalyzed 1,3‐Rearrangement/[3 + 2] Cycloaddition of Carbonyltriazoles.

Abstract

AbstractA Rh(II)‐catalyzed tandem intramolecular cyclization of aromatic aldehydes and ketones having a (1‐sulfonyl‐1,2,3‐triazolyl)methoxy side chain is developed to allow a novel synthesis of the title compounds (II), (IV), and (VI).
