    • IN WHICH R independently is hydrogen (i.e., no substitution on the phenyl ring), lower alkyl, lower alkoxy, halo or trifluoromethyl; x is 1 to 2; n is 1 to 3, and R1 and R2 independently are hydrogen, lower alkyl or phenyl and together with the nitrogen atom form a heterocycle which may contain an oxygen atom as a hetero atom. The compounds are prepared by reacting the corresponding N-substituted-1(arylthio)methanesulfonamide with small, incremental amounts up to substantially equimolar of 30% hydrogen peroxide in glacial acetic acid at 65*-70*C., to obtain the sulfinyl compound, or substantially two equimolar proportions of 30% hydrogen peroxide in glacial acetic acid at reflux temperature to obtain the sulfonyl compound, and recovering the corresponding sulfinyl or sulfonyl product. The compounds are useful as intermediates for making the dihalomethane analogs, the latter being useful as antimicrobials.

    • Pyranoindole and thiopyranoindole derivatives characterized by having an amino(lower)alkyl radical attached to either or both the 1 and 9 position of a pyrano(3,4-b)indole or thiopyrano(3,4b)indole nucleus are disclosed. The amino portion of the amino(lower)alkyl radical may be further substituted with one or two lower alkyl groups or incorporated into a heterocyclic amine radical. The derivatives having the amino(lower)alkyl radical only at position 1 are further substituted at position 1 and may be optionally substituted at positions 3,4, 5, 6, 7, 8 and 9. The derivatives having the amino(lower)alkyl radical only at position 9 possess two substitutents at position 1 and may be optionally substituted at position 3, 4, 5, 6, 7, and 8. The derivatives having an amino(lower)alkyl radical at both positions 1 and 9 are further substituted at position 1 and may be optionally substituted at positions 3,4,5, 6, 7 and 8. The pyrano- and thiopyranoindole derivatives of this invention are useful antidepressant and antiulcer agents. Methods for the preparation and use of these derivatives are also disclosed.
