合成路线1
该中间体在本合成路线中的序号:(XXIX)By allylic oxidation of vitamin D2 (XXIII) with SeO2 and tert-butyl hydroperoxide in pyridine followed by purification by TLC over silicagel. The allylic oxidation of trans-vitamin D2 (XXIX) with SeO2, tert-butyl hydroperoxide and octahydroacridine in dichloromethane gives the trans-1alpha-hydroxyvitamin D2 (XXX), which is isomerized to the target compound by irradiation with UV light with anthracene as photosensitizer.
