Acylation of amino acids with furancarboxylic acid chlorides
Lapina,Pevzner
, p. 1479 - 1483 (2007/10/03)
Acylation of aromatic amino acids with furancarboxylic acid chlorides effectively proceeds in water-acetone medium at pH 8-9. Aliphatic amino acids are acylated at higher pH values, but under these conditions hydrolysis of acid chlorides becomes the main
