Abstract
A facile synthesis of chiral 1,1′-binaphthalene-2,2′-dicarboxylic acid has been described via a three-step reaction from optically active 1,1′-binaphthalene-2,2′-diol(overall yield up to 62%,ee up to 99%).The key methoxycarbonylation of ditriflate of 1,1′-binaphthalene-2,2′-diol can be realized with air bag,avoiding the use of expensive high-pressure equipments.This optimal synthetic procedure is simple and suitable for industrial process.
