An Efficient Assembly of Heterobenzazepine Ring Systems Utilizing an Intramolecular Palladium-Catalyzed Cycloamination
摘要:
Azaheterocyclic compounds are interesting and medicinally relevant targets. Herein we disclose an improved synthesis into the oxazepine and thiazepine ring systems. The key step in the synthesis exploits recent advancements in the palladium-catalyzed amination reaction, which was utilized to form the seven-membered rings. General conditions for this reaction were Pd(2)dba(3), P(t-BU)(3), NaO-t-Bu alone or with K2CO3, in toluene. The scope of the reaction was investigated, and has been shown to be effective on a variety of substrates as illustrated.
