“…These allosteric catalysts constitute encouraging attempts towards the development of catalysts for which the activity and selectivity can be controlled reversibly along the course of the catalytic reaction. In the examples mentioned above, noncovalent interactions play an important role in the control of the process 666 and the strategy is complementary to the switchable catalysts developed so far in which the activity is controlled by 45 acid/base addition, [667][668][669] by modifying the temperature, [670][671][672][673] the magnetic force, 674,675 the wavelength, 109,147,312,[676][677][678][679][680][681][682][683] the redox potential [684][685][686][687][688] and other parameters. 689 Feringa and co-workers recently reported a system in which both the activity and enantioselectivity of an organocatalytic reaction is tuned by the 50 motion of a molecular motor.…”
