Lipophilic dialkoxybenzenesulfonic acids effectively catalyze the acid-hydrolysis of p-nitrophenyl acetate in a benzene-H20 twophase system. Examination of the effects of varying the alkyl-chain length and catalyst concentration on the rate suggests the reaction involving some micellar aggregates of
## Abstract A histidineβcontaining cyclic dipeptide, cyclo(DβLeuβLβHis), was almost 20 times as efficient a catalyst as imidazole in the hydrolysis of __p__βnitrophenyl laurate. The effect of dioxane on the hydrolysis showed that hydrophobic interaction between the cyclic dipeptide and the ester is
