A domino alkyne addition/CO insertion/Nu acylation reaction to a series of novel anthrapyran-2-ones in good to excellent yields is described. In addition, an efficient synthetic sequence involving carbonylation, formation of a β-keto-sulfoxide, and cyclization is presented en route to the antibiotic and antitumor compound (±)-BE-26554A.
描述了对一系列新型蒽蒽-2-酮的多米诺炔加成/ CO插入/ Nu酰化反应,收率良好至极佳。此外,在通往抗生素和抗肿瘤化合物(±)-BE-26554A的途中,提出了涉及羰基化,β-酮亚砜形成和环化的有效合成序列。
