• 개요

  Fluticasone 17β-carboxylic acid is an intermediate in the synthesis of the glucocorticosteroid fluticasone propionate .

• 화학적 성질

  White Solid

• 용도

  Fluticasone intermediate. Anti-inflammatory agent

• Synthesis

  To a suspension of flumethasone (1.19 g, 2.9 mmol) in tetrahydrofuran (11 ml) was added a solution of periodic acid (2.25 g, 9.9 mmol) in water (5.3 ml). The resulting solution was stirred at RT for 1 h. The tetrahydrofuran was removed in vacuo to leave an aqueous suspension which was filtered, and the solid washed with water and dried to give 1.17 g (100%) of the (6a,11b,16a,17a)-6,9-Difluoro-11,17-dihydroxy-16-methyl-3-oxoandrosta-1,4-diene-17-carboxylic acid (Fluticasone 17β-Carboxylic Acid) as a colorless solid.
