Synthesis of 3-Selena-1-dethiacephems and Selenazepines via Iodocyclization
摘要:
A convenient approach to synthesize novel selenium-beta-lactams, 3-selena-1-dethiacephems and selenazepines, was accomplished via the regioselective iodocyclization reaction. The substituent of allenyl moieties dramatically influenced the regiochemical outcome in the iodocyclization of allene-selenourea derivatives.
