A hexahydrobenzo[AB]furan characteristic of the avermectins and certain milbemycins was synthesized via acid-catalyzed intramolecular addition of a diazoketone to a γ-lactone; subsequent transformations led to structures containing much of the functionality and stereochemistry present in the corresponding segments of these macrolides.
阿维菌素和某些米尔倍霉素的六氢苯并[AB]呋喃特性是通过酸催化的双氮酮向γ-内酯的分子内加成反应合成的。随后的转化导致结构包含这些大环内酯的相应片段中存在的许多功能和立体化学。
