✦ Synopsis

Studies of the hydrolyses of m-and p-substituted ohenvl acetates showed that the well-known meta-selectivity effect occurred with 2,, while none i&is bbserved withA. This variation in selectivity was due to a change in the cayalytic rate constant caused by the substituent on B-cyclodextrin.

In the past decade, many catalytic processes modeling enzymic reactions have been extensively 1 studied by use of ct-or O-cyclodextrins ,
