A Synthesis of (±)-Ipalbidine Using Sulfur-controlled 6-Exo Selective Radical Cyclization of α-Phenylthio Amide
摘要:
A synthesis of (+/-)-ipalbidine (1) has been achieved using Bu3SnH-mediated 6-exo selective radical cyclization of 2-[3-(phenylthio)prop-2-enyl]-N-[alpha-(p-methoxyphenyl)-alpha-(phenylthio)acetyl]pyrrolidine (15) as a key step.
