Synthesis and GABAA receptor activity of 2,19-sulfamoyl analogues of allopregnanolone
The synthesis of new analogues of allopregnanolone with a bridged sulfamidate ring over the β-face of ring A has been achieved from easily available precursors, using an intramolecular aziridination strategy. The methodology also allows the synthesis of 3α-substituted analogues such as the 3α-fluoro...
