Regiospecific synthesis of 2,3-disubstituted-L-histidines and 2,3-disubstituted histamines starting from L-histidine methyl ester and histamine is reported. The key step involves homolytic free radical alkylation via silver catalyzed oxidative decarboxylation of alkylcarboxylic acids with ammonium persulfate.
报道了从L-组氨酸甲酯和组胺开始的2,3-二取代的L-组氨酸和2,3-二取代的组胺的区域特异性合成。关键步骤涉及通过过硫酸铵的银催化烷基羧酸的氧化脱羧,实现均相自由基烷基化。
