This study proposes two different methods of photocatalytic-controlled and visible light-induced selective oxidation of pyridiniums with air as the terminal oxidant. The key to these transformations is to choose the appropriate light source and photocatal
Arylalkylheterocyclic amines,N-substituted by aryloxyalkyl group in a method for allergy treatment

, (2008/06/13)
A method of inhibiting Type 1 allergic responses in a living animal body with substituted heterocyclic amines is disclosed wherein the active agents are expressed generally by the formula which includes certain known and certain known compounds: STR1 wherein P is zero, one or two; m is one to six inclusive; A is selected from hydrogen, hydroxy or cyano; d is zero or one; Q is --CH--, CH2 -- or STR2 n is zero or one and when Q is --CH-- and n is one, a double bond is formed with one of the adjacent carbons but not both at the same time, and when n and d are zero at the same time, a double bond is formed between the α carbon and a carbon of the central heterocyclic amine ring; Ar, D and R are selected from phenyl, substituted phenyl, pyridinyl, thienyl, furanyl or naphthyl and in addition, R may have the values benzyl, substituted benzyl, cycloalkyl or loweralkyl and D may additionally have the values: 2H-1-benzopyran-2-one,4-oxo-4H-1-benzopyran-2-carboxylic acid loweralkyl ester, 2,3-dihydro-4H-1-benzopyran-4-one, 1,4-benzodioxanloweralkyl-2-yl or 1,1'-biphenyl-4-yl and the pharmaceutically acceptable salts thereof.

, (2008/06/13)
Novel 1-[(heterocyclyl)alkyl]-4-diarylmethoxy piperidine derivatives are disclosed having the formula STR1 where n is 2-6, Ar1 and Ar2 are aryl and B is a substituted benzimidazolyl radical. These compounds are useful for their antianaphylactic and antihistaminic properties. Specific claimed compounds are 1-{3-[4-(diphenylmethoxy)-1-piperidinyl]-propyl}-1,3-dihydro-2H-benzimidazol-2-one, 1-{2-[4-(diphenylmethoxy)-1-piperidinyl]ethyl}1-, 3-dihydro-2H-benzimidazol-2-one, and 1-{4-[4-(diphenylmethoxy)-1-piperidinyl]butyl}-1,3-dihydro-2H-benzimidazol-2-one.
