Unprecedented synthesis of aza-bridged benzodioxepine derivatives through a tandem Rh(II)-catalyzed 1,3-rearrangement/[3+2] cycloaddition of carbonyltriazoles

Unprecedented synthesis of aza-bridged benzodioxepine derivatives through a tandem Rh(II)-catalyzed 1,3-rearrangement/[3+2] cycloaddition of carbonyltriazoles

Rh(II)-catalyzed novel tandem intramolecular cycloisomerizations of aldehydes or ketones with 1-sulfonyl 1,2,3-triazoles have been disclosed, providing a facile protocol to access a series of functionalized aza-bridged benzodioxepine heterocycles.
