  Synthesis and Biological Activity of 11,19-Bridged Progestins 11This paper is dedicated to Prof. R. Wiechert on the occasion of his 70th birthday.

  摘要：

  A synthetic approach to 11,19-bridged progestins is described. The key step in the synthesis is a 6-endo-trig radical cyclisation. The new progestins were rested for their biological activities in vitro and in vivo and compared to those of known progestins. (C) 1998 by Elsevier Science Inc.
