โœฆ Synopsis


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.
