  Practical synthesis of androgen: the efficient transformation of 17-oxo group to 17α-hydroxy group

  摘要：

  The present report describes the improved transformation of the 17-oxo group in 3 beta-acetoxy-5 alpha-androstan-17-one to a 17 alpha-hydroxy group. A mixture of 17 alpha-acetoxy and 16-ene compounds, which are usually produced by the standard synthetic route, were treated with peracetic acid (epoxidation of the 16-ene compound) and then sodium hydroxide (reduction-hydrolysis) to give the desired 17 alpha-hydroxy compound in much better yield than that in previous reports. Recrystallization of the crude product with cyclohexane-methanol gave the pure compound in 54% yield (total yield from starting ketone). (Steroids 63:630-632). (C) 1998 by Elsevier Science Inc.
