Dipyrano-quinolinones useful as anti viral agents and a process for preparing the same

Abstract

The invention relates to novel dipyrano-quinolinone class of compounds having the general formula: Wherein R is hydrogen, alkyl optionally substituted about C-1 to C-10 alkenyl optionally substituted about C-1 to C-10 with one or more double bounds, alkynyl optionally substituted about C-1 to C-10 with one or more triple bonds, aryl, hetero aryl, carbocyclic aryl, alkyl aryl, alcyclic compounds, C-1 to C-6 alkyl with terminal dialkyl amino group, thio alkyl, hydroxyl alkyl groups; R1 is H, lower dialkyl amino alkyls such as methyl, ethyl, propyl, and other alkyl groups or b-amino acid moieties, hydroxy alkyl groups having optionally substituted about C-1 to C-10 carbons, acid amides such as aliphatic acids, aromatic acids, sulphonic acids trihalo acids. x—x is either a carbon-carbon single bond or a carbon-carbon double bond; R2 and R3, R4 and R5 are each independently hydrogen and methyl there by resulting the cis and trans diastereomers as well as enantiomers; R4 and R5 are each independently hydrogen and methyl while R6 and R7 are each independently hydrogen and hydroxyl/—OR8, where R8 is independently alkyl, aryl alkyl, amino alkyl, hydroxy alkyl with C-1 to C-10 carbons, sugars which include mono saccharides both in the furanose form as well as pyranose form, amino sugars, disaccharides, amino acids, small peptides through lower alkyl spacer groups, thereby resulting the cis and trans diastereomers as well as enantiomers; and a process for producing the above novel dipyrano-quinolinone class of compounds.
