Butyryl adenylate

The chemical synthesis of several mixed anhydrides such as DPN SS6), XJDP-glucose (336), butyryl adenylate (336a), and amino acid adenylates (336b) have been reported. Cytidine diphosphate choline was formed in good yield by condensing phosphorylcholine with cytidine 5 -... 

A.7.1 Esterification of Acids using Carbodiimides. The formation of anhydrides from carboxylic acids, thiocarboxylic acids, sulfonic acids and phosphorous acids are discussed in Section 2.4.S.2. In this section only special cases of anhydride formation are described. Mixed anhydrides of amino acids and adenylic acid are produced from the corresponding acids using DCC as the condensation agent. ° Mixed anhydrides not containing amino acids, such as butyryl adenate, adenosine 5 -phosphosulfate and p-nitrophenyl-thymidine-5-phosphate are also obtained.
