A convenient synthesis of 1,3,4,5-tetrahydro-2H-3-benzazepin-2-ones by acid-catalyzed cyclization of N-(2-arylethyl)-N-methyl-2-sulfinylacetamides.

Abstract

1, 3, 4, 5-Tetrahydro-3-methyl-2H-3-benzazepin-2-one derivatives were synthesize by acid-catalyzed cyclization of N-(2-arylethyl)-N-methyl-2-sulfinylacetamides. Some chemical transformations of the 2H-3-benzazepin-2-ones are also described.
