A highly efficient, two-stage, continuous-flow synthesis of vitamin D 3 from provitamin D3 was achieved. The developed method afforded the desired product in high yield (HPLC-UV: 60%, isolated: 32%) and required neither intermediate purification nor high-dilution conditions.

Determination of the Molar Absorptivity (ε) of the Photoisomers of 3β-Hydroxy-cholest-5,7-diene (Provitamin D3)

A method is described which allows the determination of the molecular absorptivity (ε) of all components in a four-component system and is applied to the ε-determination of the photoisomers of provitamin D3 (1): praevitamin D3 (2), lumisterol3 (3), and tachysterol3 (4).By means of irradiation with appropriate wavelengths the four-component system is reduced to a two- and a three-component system, respectively, and the unknown molar absorptivities are evaluated numerically or graphically.
