A convenient AB-ring segment for β-rhodomycinone, β-isorhodomycinone, α2-rhodomycinone, and α-citromycinone using a novel oxygenation reaction
Abstract
An unusual bishydroxylation of 2-ethyl-5,8-dimethoxy-7-bromo-1-tetralone gives an AB-ring segment suitable for elaboration to certain anthracyclinones.
