PROCEDURE
实验过程
For the removal of both acetyl protective groups, 700 mg (1.4 mmol) of 3,7β-diacetoxy-2-iodo-estra-1,3,5(10)-trien-17-one, dissolved in 20 ml of methanol, was mixed with 200 mg of sodium methanolate, and the solution was stirred overnight. Then, it was mixed with 2.5 g of Amberlite IR-120, stirred for 30 minutes, filtered, and the solution was concentrated by evaporation in a rotary evaporator. Flash chromatography (cyclohexane/ethyl acetate) yielded 396 mg (68%) of colorless crystals.
