As a model study for the synthesis of anisatin, 2-oxaspiro[3.5]nonane and 5-hydroxy-5-methyl-2-oxaspiro[3.5]nonane were synthesized from methyl cyclohexanecarboxylate and 2-ethoxycarbonylcyclohexanone, respectively, and these oxetanes were submitted to ruthenium tetroxide oxidation to afford the corresponding β-lactones.
作为合成茴香素的模型研究,分别从环己烷羧酸甲酯和 2-乙氧羰基环己酮合成了 2-氧杂螺[3.5]壬烷和 5-羟基-5-甲基-2-氧杂螺[3.5]壬烷,并提交了这些氧杂环丁烷四氧化钌氧化得到相应的β-内酯。
