Base-free enantioselective S(N)2 alkylation of 2-oxindoles via bifunctional phase-transfer catalysis
N-Protected oxindole derivatives of unprecedented malleability bearing ester moieties at C-3 have been shown to participate in enantioselective phase-transfer-catalysed alkylations promoted by ad-hoc designed quaternary ammonium salts derived from quinine bearing hydrogen-bond donating substituents....
