A practical protocol for the synthesis of dibenzo[b,e][1,4]oxazepin-11(5H)-ones has been developed. By virtue of Pd-catalyzed aminocarbonylation and aromatic nucleophilic substitution, 61 examples of the desired dibenzoxazepinones were obtained in moderate to excellent isolated yields (54-92%).

A simple and efficient methodology for the synthesis of pyrido‐fused quinazolinones and dibenzoxazepinones has been developed. By palladium‐catalyzedcarbonylation/nucleophilic aromatic substitution reaction sequence, and with 1‐chloro‐2‐fluorobenzenes and 2‐aminopyridines or 2‐aminophenols as the starting materials, good yields of the desired products were be obtained.

The present invention provides novel compounds of Formula I:
The invention further relates to pharmaceutical compositions comprising compounds of Formula I and to methods of using compounds of Formula I to treat neuropsychiatric disorders (e.g., psychosis, depression, schizophrenia).
An unprecedented highly stereoselective synthesis of pyrrolo[1,2-d][1,4]oxazepin-3(2H)-ones has been accomplished via photoredox/N-heterocycliccarbene (NHC) relay catalysis. A wide range of substituted dibenzoxazepines and aryl/hetereoaryl enals were well accommodated under the organic photoredox catalysis-promoted amine oxidation to generate the imines, followed by a NHC-catalyzed [3 + 2] annulation
通过光氧化还原/ N-杂环卡宾 (NHC) 中继催化,实现了前所未有的高度立体选择性合成吡咯并 [1,2- d ][1,4]oxazepin-3(2 H )-ones。有机光氧化还原催化促进胺氧化生成亚胺,然后进行 NHC 催化的 [3 + 2] 环化反应,以实现优异的非对映和对映选择性二苯并恶氮杂合吡咯烷酮。
