Abstract
Indenopyran- and indenothiopyranalkylamine derivatives characterized by having an amino(lower)alkyl radical attached to the 1 position of an indeno[2,1-c]pyran or indeno[2,1-c]thiopyran nucleus are disclosed. Also included are the corresponding derivatives having an indeno[1,2-c]pyran and an indeno[1,2-c]-thiopyran nucleus. The amino portion of the amino(lower)alkyl radical may be further substituted with one or two lower alkyl groups or incoporated into a heterocyclic amine radical. The derivatives are further substituted at position 1 and may be optionally substituted at positions 3, 4, 5, 6, 7, 8, and 9. The indenopyran- and indenothiopyranalkylamine derivatives of this invention are useful antidepressant agents. Methods for their preparation and use are disclosed.
