  There are disclosed certain novel compounds identified as benzo-fused lactams which promote the release of growth hormone in humans and animals. This property can be utilized to promote the growth of food animals to render the production of edible meat products more efficient, and in humans, to increase the stature of those afflicted with a lack of a normal secretion of natural growth hormone. Growth promoting compositions containing such benzo-fused lactams as the active ingredient thereof are also disclosed.

  A new approach for the synthesis of 2-hetaryl derivatives of 3-oxo-3,4-dihydro-2H-1,4-benzothiazines is described. 2-Chloro derivatives of 2a,b were reacted with electron-rich heterocycles 3-14 under basic catalysis (with a slight excess of Et3N) to provide the substitution products 16-36. In the reaction of 2b with 14 and 15, an intermolecular cyclization took place between the amino and ethoxycarbonyl groups, resulting in spiro compounds 35 and 36, respectively.
