Regioselective Synthesis of Fused Oxazepinone Scaffolds through One-Pot Smiles Rearrangement Tandem Reaction
摘要:
The paper describes a convenient and facile methodology for the regioselective synthesis of fused oxazepinone scaffolds. This process is an efficient construction of the oxazepinone scaffold by a one-pot coupling/Smiles rearrangement/cyclization approach. This transition metal-free process has potential applications in the synthesis of biologically and medicinally relevant compounds.
Fused pyridazino[4,5-b][1,4]oxazepine-diones were easily obtained in moderate to excellent yields via Smiles rearrangement. The synthetic approach is supported by a one-pot couplingSmiles rearrangement-cyclization process. This process has potential applications in the synthesis of biologically and medicinally relevant compounds.
