Compounds having the general formula: ##SPC1## Wherein R.sup.1 and R.sup.2 represent hydrogen, halogen, lower alkyl, lower alkoxy, or nitro, and wherein R.sup.1 and R.sup.2 may be the same or different. R.sup.3 may be hydrogen or lower alkyl, and X and Y may be one or two. They have been found to be useful sedative type depressants of the central nervous system. Most of the compounds having the general formula indicated above are new but others such as 2,3-dihydrospiro[naphthalene-1(4H),3'-piperidine]-2',4,6'-trione which has useful sedative properties have been reported in the literature.
