In search of potent and selective 5-HT2C receptor agonists, a series of novel 3-substituted 1-methyl-3-benzazepin-2-ones and 8-chloro-1-methyl-3-benzazepin-2-ones have been synthesized and evaluated for their 5-HT2C receptor agonistic potential.
Pyrido[2,3-b][1,4]oxazin-2-ones are conveniently prepared in excellent yields by a one-pot annulation of N-substituted-2-chloroacetamides with 2-halo-3-hydroxypyridines with use of cesium carbonate in refluxing acetonitrile. The key transformation features a Smiles rearrangement of the initial O-alkylation product and subsequent cyclization.
