    摘要: According to this process, one effects a stereospecific reduction of the two hydroxyl groups of an ether-diol by a mixture (titanium trichloride, lithium aluminum hydride) at a temperature between 5.degree. C. and about 40.degree. C. and that optionally, one converts the resulting ether into vitamin A, retinol or retinoic acid.Application to the synthesis of all-trans compounds selected from the group consisting of vitamin A and its ethers, retinol and retinoic acid, and their 13-cis isomers.
