摘要:The present invention relates to a process for the preparation of steroidal 17β-carboxylic thioates. More particularly the present invention relates to a convenient and efficient synthesis of steroidal 17β-carboxylic thioates, such as fluticasone propionate I, using soluble mixed fluorides to introduce fluorine by displacing an appropriate leaving group X in compounds II resulting in selective and controlled fluorination. The present invention also relates to intermediates II and their preparation.
