Abstract
The photochemical conversion of isotachysterol2 (in ether) has been studied; the effects of wave‐length and time of irradiation on the composition of the irradiation mixture are discussed. On chromatography of the crude irradiation product a compound was obtained in a pure, non‐crystalline form. The compound did not show antirachitic activity. The ultra‐violet and infra‐red absorption spectra, the iodine‐catalysed quantitative conversion to isotachysterol2, the behaviour on heating in solution and the very low reactivity towards maleic anhydride led to the conclusion that the compound is the Δ6,7‐cis isomer of isotachysterol2, i.e. 9,10‐secoergosta‐5(10),6‐cis, 8(14), 22‐tetraen‐3β‐ol.Keywords
