Thioesters are compounds with the functional group C-S-CO-C. They are the product of esterification between a carboxylic acid and a thiol. Thioesters are widespread in biochemistry, the best-known derivative being acetyl-CoA. ==Synthesis== Thioesters have been prepared in many ways, but the main route involves condensation of thiols and carboxylic acids in the presence of dehydrating agents:〔(【引用サイトリンク】 Synthesis of thioesters )〕 :RSH + R'CO2H → RSC(O)R' + H2O A typical dehydration agent is DCC or related reagents. Acid anhydrides and some lactones also react with thiols in the presence of base. Thioesters can be conveniently prepared from alcohols by the Mitsunobu reaction, using thioacetic acid. They also arise via carbonylation of alkynes and alkenes in the presence of thiols. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「thioester」の詳細全文を読む スポンサード リンク
