    摘要: The invention relates to a new process for the synthesis of 17&bgr;-hydroxy-17&agr;-methyl-1,3-seco-2-nor-5&agr;-androstane-3-acid derivatives of formula (I) wherein the meaning of Z is carboxyl or formyl group and to the new secoindoxylidene carboxylic acid derivatives of formula (II) wherein R1 and R2 independently are C1-C4 alkyl or alkoxy group, hydrogen or halogen atom—which are intermediates for preparing the compounds of formula (I). The 17&bgr;-hydroxy-17&agr;-methyl-1,3-seco-2-nor-5&agr;-androstane-3-acid derivatives of formula (I) are intermediates in the synthesis of oxandrolon (17&bgr;-hydroxy-17&agr;-methyl-2-oxa-5&agr;-androstane-3-one), which is used as anabolic in therapy.
