Novel synthetic approaches to the palmarumycin skeleton
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 giv
