A highly regioselective Minisci reaction with the decarboxylative alkylation of purinenucleosides under mild conditions was developed. With 5 mol % AgNO3 as a catalyst and (NH4)2S2O8 as an oxidant, a series of purinenucleosides including ribosyl, deoxyribosyl, arabinosyl purinenucleosides worked well with primary, secondary, and tertiary aliphatic carboxylic acids.
开发了在温和条件下具有嘌呤核苷脱羧烷基化的高度区域选择性Minisci反应。以5 mol%的AgNO 3为催化剂,以(NH 4)2 S 2 O 8为氧化剂,一系列嘌呤核苷,包括核糖基,脱氧核糖基,阿拉伯糖基嘌呤核苷,与伯,仲和叔脂肪族羧酸配合得很好。
