标题:New Tetracyclic 1,4-Oxazepines Constructed Via Practically Simple Tandem Condensation Strategy From Readily Available Synthons
摘要:A Streamlined Synthetic Methodology Towards Novel Tetracyclic 1,4-Oxazepines From Readily Available Precursors Is Described. The Compounds,Designed As More Soluble Version Of The Earlier Described,Poorly Soluble Dibenzo[bf][1,4]Oxazepines,Were Obtained In High Yields And As A Single Regioisomer As A Result Of Three Tandem Chemical Events-Nucleophilic Aromatic Substitution,Smiles Rearrangement And Denitrocyclization.
