title: Total synthesis of (+)-yatakemycin.
abstract: A convergent total synthesis of (+)-yatakemycin was 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.
