Abstract

-n-Butylaminolysis of cis 2-hydroxy-cyclopentyl benzoylglycinate (a simple model of peptidyl- t-RNA) in MeCN occurs ca 300 times faster than that of cyclopentyl benzoylglycinate. This acceleration caused by the neighbouring cis 2-hydroxy group is considerably larger than found in aqueous media for similar reactions. Trans 2-hydroxy and cis or trans 2-methoxy groups also accelerate the aminolysis, but less efficiently. Comparison between the ...
