Synthesis of 3/gb-acetoxy-24-norchola-5,20(22)-dien-23-al. a new intermediate for an improved synthesis of [24-14c]-cholesterol
[24-14C]-Cholesterol was synthesized by reaction between the phosphorane derivative of [1-14C]-isobutyltriphenylphosphonium bromide and 3β-acetoxy-24-norchola-5,20(22)-dien-23-al (IX) followed by hydrogenation of the condensation product. The intermediate IX was prepared by two different procedures...
