| Abstract: | Cyclohexaamylose-N-(N,N′-dimethylaminoethyl)acetohydroxamic acid and cyclohexaamylose-N-(4-imidazolemethyl)acetohydroxamic acid were synthesized. Their catalytic power is greater than that of cyclohexaamylose or of cyclohexaamylose-N-methylhydroxamic acid. In addition, optical selectivity was exhibited in the hydrolysis of d- and l-acetylphenylalanine p(m)-nitrophenyl esters by cyclohexaamylose-N-(N,N′-dimethylethyl)acetohydroxamic acid, and cycloheptaamylose. |
