Synthesis of phenanthridin-3-one derivatives: Non-steroidal inhibitors of steroid 5-α-reductase
摘要:
A short and efficient six-step synthesis of novel phenanthridin-3-one derivatives is described. The synthesis of these derivatives is highlighted by the cyclization of a suitably placed ketone side chain with a thioiminium ion. The derivatives prepared were found to be inhibitors of human steroid 5-alpha reductase.

the synthesis of primary amides has long been an elusive aim. Here, we report an efficient catalytic system which enables inexpensive NH4Cl to be utilized as a practical alternative to gaseous ammonia for the palladium-catalyzed alkene-hydroaminocarbonylation reaction. Through appropriate choice of the palladium precursors and ligands, either branched or linear primary amides can be obtained in good
