Unprecedented synthesis of aza-bridged benzodioxepine derivatives through a tandem Rh(ii)-catalyzed 1,3-rearrangement/[3+2] cycloaddition of carbonyltriazoles?
Chemical Communications Pub Date: 2014-11-04 DOI: 10.1039/C4CC08339C
Abstract
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.
