摘要:
Anthrarufin (4) has been converted by a high-yielding route involving sequential reductive Claisen rearrangements into 1-acetoxy-5-methoxy-9,10-dioxo-6-(2''-oxopropyl)-9,10-dihydroanthracene-2-carbaldehyde (3), an intermediate which is suitable for the synthesis of vineomycins. The thermal Claisen rearrangements of some allyl ethers of 1,5-dihydroxyanthraquinone have been examined.
