Abstract
1447456 Preparation of desmosterols TEIJIN Ltd 14 June 1974 [20 June 1973 3 July 1973] 26590/74 Heading C2U Desmosterol derivatives of the formula (wherein R is a mono- or di-valent protecting group and n is 1 or 2) are preapred by dehydration of 24-hydroxycholesterol derivatives of the formula using P 2 O 5 , POCl 3 , SOCl 2 , KHSO 4 or an organic sulphonyl chloride. They may subsequently be converted to desmosterol by known methods.
