  摘要：

  The measurement of serum/plasma levels of 1 alpha,25-dihydroxyvitamin D-3 1a is important for the diagnosis of diseases influencing vitamin D metabolism. To obtain antibodies to the metabolite 1a which are highly specific and useful for development of immunoassays, two novel haptenic derivatives. 11 alpha-(3-carboxypropanoyloxy)-1 alpha,25-dihydroxyvitamin D-3 2a and 11 alpha-(4-carboxybutanoyloxy)-1 alpha,25-dihydroxyvitamin D-3 2b were synthesized each in 19 steps from a suitably protected derivative (3) of 11 alpha,25-dihydroxycholesterol.
