Enzyme-like enantioselective catalysis over chiral ‘molecular footprint’ cavities on a silica (alumina) gel surface
Abstract
Chiral catalytic cavities were imprinted on a silica gel surface using a chiral template, N-benzoyl-(Nα-benzyloxycarbonyl)-L- alanineamide, by an imprinting procedure; these cavities display enatioselective catalysis in 2,4-dinitrophenolysis of the corresponding substrate, benzoic N-benzyloxycarbonyl-L-alanine anhydride.
