The synthesis of macrocyclic lactones related to zearalanone is described. The reaction of salicylic acids with 1,9-dibromononane, 1,9-dichloro-5-oxanonane, and 1,9-dibromononan-5-one was used to prepare the corresponding lactones. Cyclisation of 2-(9-hydroxynonyloxy)benzoic acid, 4,6-dibenzyloxy-2-(9-hydroxynonyloxy)benzoic acid, and 4-benzyloxy-2-hydroxy-6-(9-hydroxy-5-oxodecyloxy)benzoic acid using
描述了与泽拉丙酮有关的大环内酯的合成。将水杨酸与1,9-二溴mononane,1,9-二氯-5-氧杂壬烷和1,9-二溴一南-5-酮的反应用于制备相应的内酯。2-(9-羟基壬基氧基)苯甲酸,4,6-二苄氧基-2-(9-羟基壬基氧基)苯甲酸和4-苄氧基-2-羟基-6-(9-羟基-5-氧代癸氧基)苯甲酸的环化使用偶氮二羧酸二乙酯-三苯基膦以中等收率得到相应的内酯。
