A process for producing vitamin D3 or its acylate characterized by irradiating a solution of a 7-dehydrocholesterol acylate with ultraviolet rays so as to be photoisomerized to produce a previtamin D3 acylate. A process for the synthesis of an all-trans compound selected from the group consisting of vitamin A and its ethers, retinol and retinoic acid, and their 13-cis isomers comprising effecting stereospecific reduction of the two hydroxyl groups of an ether-diol, precursor of vitamin A with a mixture of 2 equivalents of titanium chloride and 1 equivalent of lithium aluminum hydride in an anhydrous solvent medium at a temperature between 5° C. and about 40° C. and optionally converting the resulting ether into vitamin A, retinol or retinoic acid.
