accomplished in a 20-step sequence in an overall yield of 13%. The synthesis features the regioselective ring opening of (S)-epichlorohydrin with 2,6-dibromophenyllithium species, the mild copper-mediated aryl amination utilizing the combination of CuI and CsOAc, and the efficient deprotection of benzyl groups of aryl benzyl ether with BCl3 in the presence of pentamethylbenzene.
(+)-yatakemycin 的收敛全合成以 20 步的顺序完成,总产率为 13%。该合成的特点是 (S)-表氯醇与 2,6-二溴苯基锂物种的区域选择性开环,利用 CuI 和 CsOAc 的组合进行温和的铜介导的芳基胺化,以及芳基苄基醚的苄基与 BCl3 的有效脱保护五甲苯的存在。
