Duguet, Nicolas M. Z. Slawin, Alexandra Smith, Andrew D. An Asymmetric Hetero-Claisen Approach to 3-Alkyl-3-aryloxindoles The reaction of a chiral <i>N</i>-phenylnitrone derived from Garner’s aldehyde with alkylarylketenes generates 3-alkyl-3-aryloxindoles directly in excellent yields and with good to excellent levels of enantioselectivity (up to 90% ee). enantioselectivity;ee;yield;Approach;Asymmetric;aldehyde;alkylarylketene;Alkyl;chiral;alkyl;Garner 2009-09-03
