Abstract

NEW MATERIAL:24-Hydroxyisotachysterol3 of formulaI.
USE: Activated form of vitamin D3 analog. It can accelerate the calcium absorption from small intestine even in animals removed kidney and can increase the concentration of calcium in blood.
PREPARATION: 24-Hydroxyvitamin D3 of formula II is brought into contact with boron trifluoride ether complex in an inert solvent to isomerize to form the compound of formulaI. The compound of formula II is readily provided by the irradiation with ultraviolet rays and isomerization of 3β, 24-dihydroxycholesta-5,7-diene that is prepared from cholesterol of formula III through 24-oxocholesterol, 3β, 24-diacetoxychloesterol-5-ene.
