摘要:
THE PRESENT INVENTION RELATES TO SUBSTITUTED-O-HYDTROXYW-(METHYLSLFINYL) ACETOPHENONES OF THE FORMULA 1
CH3-SO-CH2-CO-Z(-R1)(-R2)-OH
WHEREIN Z IS AN AROMATIC OR HEREROAROMATIC NUCLEUS SUCH AS BENZENE NAPHTHALENE, ANTHARACENE, PHENANTHRENE, PYRIDINE, QUINOLINE ISOQUINOLINE, CARBAZOLE, BENZOTHIAZINE, AND THE LIKE, WHEREIN R1 IS HALOGEN, LOWER ALKOXY, HYDROXY, ACETAMINO, ALKYL ARALKYL OR ARYL; R2 IS HYDROGEN HALOGEN, HYDROXY ALKYL OR ARYL; OR R1 AND R2 TAKEN TOGETHER MAY FORM A 1,3-DIOXOLE RING. THE COMPOUNDS OF THE PRESENT INVENTION ARE USEFUL AS INTERMEDIAES FOR THE PRODUCTION OF CHROMONED WHICH EXHIBIT ANTIALLERGENIC PROPERTIES.

WHEREIN R1 IS HALOGEN, CYANO, CARBOXY, CARBOXAMIDE, AMINO, ALKYLAMINO, ARYLAMINO, ALKOXY, N-ALKYLHYDROXYLAMINO, ACYLOXY, AMIDO AND IMIDO; R2 IS HYDROGEN, HALOGEN, LOWER ALKOXY; AND R3 IS AMINO, ALKYLENDIAMINO SUCH AS ETHYLENEDIAMINO, ETC., CYCLIC DIAMINO SUCH AS PIPERAZINE-1,4-DIYL-HYDROXYLAMINO, -O- OR -S-. THEY ARE USEFUL IN PREVENTING ALLERGIC MANIFESTATIONS. COMPOUNDS OF THIS TYPE ARE PREPARED FROM 3-(HYDROXYMETHYL)CHROMONES.
摘要:
Novel pyrano(3,2-c)(1,2)benzothiazine 6,6-dioxides are disclosed, substituted on the 3 position by a lower alkyl, carboxaldehyde, or hydroxymethyl group and, optionally substituted on the 5 position by a lower alkyl group. The corresponding aldehyde thiosemicarbazone derivatives of these compounds are also disclosed. Pharmaceutical compositions containing the substituted pyrano(3,2-c)(1,2)benzothiazine 6,6dioxides of this invention are useful in the treatment of hyperacidity; certain of these compounds also demonstrate antiallergy activity.

AND A NOVEL PROCESS FOR PRODUCING THEM. The compounds of the present invention are useful as intermediates for the production of chromones which are useful for the treatment of allergic conditions and for the treatment of hyperacidity.
wherein the Z ring has one of the following structures:
The present invention relates to ortho-hydroxy- omega (methylsulfinyl)acetonaphthones of the formula I:
摘要:
THE PRESENT INVENTION RELATES TO COMPOUNDS OF TYPE I:
3-(HO-CH2-),4-(O=),R1,R2-CHROMAN
WHEREIN R1 AND R2 ARE HYDROGEN, HALOGEN, ALKYL, ARALKYL, ARYL, ALKOXY, ACYLAMINO, HYDROXY, OR TAKEN TOGETHER R1 AND R2 FROM AN AROMATIC RING. THESE COMPOUNDS ARE PREPARED FROM THE CORRESPONDING O-HYDROXY-$(METHYLSULFINYL)ACETOPHENONES. THESE COMPOUNDS ARE USEFUL IN ALLEVIATING ALLERGIC MANIFESTATIONS.
