The Steglich esterification is a variation of an esterification with dicyclohexylcarbodiimide as a coupling reagent and 4-dimethylaminopyridine as a catalyst. The reaction was first described by Wolfgang Steglich in 1978. It is an adaptation of an older method for the formation of amides by means of DCC (dicyclohexylcarbodiimide) and 1-hydroxybenzotriazole (HOBT). 網頁2024年10月2日 · Steglich酯化反应，是指用DCC作偶联试剂，DMAP作催化剂促进的酯化反应，反应由Wolfgang Steglich在1978年首先报道。. 此反应可看作是早先用DCC和HOBT促进酰胺形成的一种变体。. 反应一般在室温下进行，常用溶剂为二氯甲烷，条件温和，可用于位阻大和对酸敏感底物的 ...
