Abstract: An enantioselective cyclization of diazoindolinones with o-hydroxymethyl chalcones has been established by a cooperative dirhodium complex and chiral phosphonic acid catalysis under mild conditions. This reaction is the first example of catalytic asymmetric intramolecular Michael-type… read more here.
