PROCEDURE

实验过程

A mixture of 2.35 g of 17α-acetoxy-6β-chloro-7α-mesyloxy-2-oxa-4-pregnene-3,20-dione, 0.83 g of potassium acetate and 0.88 ml of dimethyl sulfoxide was stirred at room temperature for 12 hours. Ice-cooled water was poured into the reaction mixture, and the precipitated crystals were collected by filtration to give 1.37 g of 17α-acetoxy-6-chloro-2-oxapregna-4,6-diene-3,20-dione. The 1H NMR spectrum of this compound was the same as that of the compound produced in Example 1.
