Oxidation of readily available aminonaphthols 7a and 7b with activated manganese dioxide gives palmarumycin analogues 8a and 8b in good yield. The related benzoquinone monoacetals 10a–c undergo cycloaddition with 3-methoxy-2-pyrone at high pressure to give adducts 12a–c, also possessing the palmarumycin framework.
容易得到的氨基萘7a和7b用活化的二氧化锰氧化可得到高产率的棕榈霉素类似物8a和8b。相关的苯醌单缩醛10a – c与3-甲氧基-2-吡喃酮在高压下进行环加成反应,得到加成物12a – c,也具有棕榈金霉素骨架。
