A 1-substituted-3-permissibly-substituted-6 (or 7)-oxodecahydroquinoline is converted to the corresponding 7 (or 6)-formyl derivative. The 6-oxo-7-formyl compound, upon treatment with hydrazine, is cyclized to a tautomeric mixture of 5-substituted-7-permissibly-substituted-4,4a,5,6,7,8,8a,9-octahydro-1H (and 2H)-pyrazolo[3,4-g]quinolines.
