    3-Menthoxybiphenyl-4-carboxylic acid: a versatile resolving agent and reagent for determination of the absolute configuration of benzylic alcohols
    摘要:
    A versatile reagent for the chiral resolution and determination of the absolute configuration of benzylic alcohols, (-)-3-menthoxybiphenyl-4-carboxylic acid, is reported. (-)-3-menthoxybiphenyl-4-carboxylic acid was condensed with racemic benzylic alcohols to yield diastereomeric 3-menthoxybiphenyl-4-carboxylic esters, which were separated by reversed-phase HPLC. The absolute configurations of the 3-menthoxybiphenyl-4-carboxylic esters were unambiguously determined by exciton-coupled circular dichroism. Hydrolysis of the 3-menthoxybiphenyl-4-carboxylic esters yielded enantiopure alcohols, and their absolute configurations were simultaneously determined. (C) 2017 Elsevier Ltd. All rights reserved.

    Asymmetric reduction of 2-acetyl-5, 8-dimethoxy-3, 4-dihydronaphthalene (1) with a novel modified hydride, originally prepared by partial decomposition of lithium aluminum hydride with (1R, 2S)-(-)-N-methylephedrine (1.0 eq) and N-ethylaniline (2.0 eq), was found to proceed highly stereoselectively, giving (S)-(-)-2-1'-hydroxyethyl-5, 8-dimethoxy-3, 4-dihydronaphthalene ((S)-(-)-2) in 100% chemical and 92% optical yields. Direct recrystallzation of (S)-(-)-2, 92% e.e., afforded optically pure (S)-(-)-2 in 87% yield based on 1. Optically pure (S)-(-)-2 was converted to (R)-(-)-2-acetyl-5, 8-dimethoxy-1, 2, 3, 4-tetrahydro-2-naphthol ((R)-(-)-3), 100% e.e., a versatile key intermediate for optically active anthracyclinone synthesis, in a good overall yield according to the reaction scheme established in the preceding paper. Synthesis of optically pure (+)-4-demethoxydaunomycinone ((+)-4d) and (+)-4-demethoxyadramycinone ((+)-4c) was accomplished by using optically pure (R)-(-)-3 as a starting material and by following the reported synthetic scheme with slight modifications.
