A number of 2-substituted pyrazinopyridoindoles (3,6-12) have been prepared by the condensation of 1,2,3,4,6,7,12,12a-octahydropyrazinopyridoindole (1) with appropriate halogen compounds.Treatment of 1 with ethylene oxide gives 4 which on condensation with p-fluorobenzoyl chloride yields 5.The corresponding 2-γ-(p-fluorobenzoyl)propyl-6-oxo-octahydropyrazinopyridoindole (14) is prepared by the oxidation of 1 with mercuric acetate followed by condensation of the resulting 6-oxo derivative (13) with γ-chloro-p-fluorobutyrophenone. 1-Oxo-2-substituted-pyrazinopyridoindoles (16-18) are prepared by the reaction of ethylene oxide on methyl 1,2,3,4-tetrahydropyridoindole-3-carboxylate followed by condensation of the resulting oxazino derivative (15) with amines.These compounds show tranquillizing, anti-inflammatory and diuretic activities.
