Résumé du colloque

To ascertain the exact fate of the C-19 during the biological conversion of androgens to estrogens it was necessary to synthesize C-19 labeled androgens. The conversion of 19-tosyloxyandrost-4-ene-3,17-dione to 5, 19-cycloandrostane-3,17-dione by various methods and opening of the cyclopropane ring with H3 2 O in presence of a trace of acid or base to androst-4-ene-3,17-dione-19-H3 will be discussed. Preparation of 19-C14 material from methyl 17-acetoxy-3,5-seco-4,19-bisnorandrostan-5-one-3-oate will also be described.
