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.
本发明涉及一种新型的二吡喃-喹啉酮类化合物,其通式如下:其中R为氢、烷基(可选地在C-1至C-10上取代)、烯基(可选地在C-1至C-10上取代,具有一个或多个双键)、炔基(可选地在C-1至C-10上取代,具有一个或多个三键)、芳基、杂环芳基、碳环芳基、烷基芳基、脂环化合物、带有末端二烷基氨基基团的C-1至C-6烷基、硫代烷基、羟基烷基基团;R1为H、较低的二烷基氨基烷基,如甲基、乙基、丙基,以及其他烷基或b-氨基酸基团、具有可选地在C-1至C-10碳上取代的羟基烷基、酸酰胺,如脂肪酸、芳香酸、磺酸三卤代酸;x-x是碳-碳单键或碳-碳双键;R2和R3、R4和R5各自独立地为氢和甲基,从而产生顺式和反式异构体以及对映体;R4和R5各自独立地为氢和甲基,而R6和R7各自独立地为氢和羟基/—OR8,其中R8独立地为烷基、芳基烷基、氨基烷基、具有C-1至C-10碳的羟基烷基、糖,包括呋喃糖和吡喃糖形式的单糖、氨基糖、二糖、氨基酸、通过较低的烷基间隔基团形成的小肽,从而产生顺式和反式异构体以及对映体;以及一种制备上述新型二吡喃-喹啉酮类化合物的方法。
