Patent ID: 7932379

Claim:
A method of forming a C-aryl glucoside of Formula VII comprising reacting a compound of Formula (VI) with a reducing reagent; wherein R 1 is selected from the group consisting of hydrogen, hydroxy, bromine, chlorine, fluorine, alkyl, alkoxy, alkylthio, and arylthio, where p is an integer from 1 to 4, and with the proviso that bromine, chlorine and fluorine, when present, are only present in at least one of the 3-, 4- and 5-positions; R 2 is selected from the group consisting of hydrogen, hydroxy, chlorine, fluorine, alkyl, alkoxy, and alkylthio, where q is an integer from 1 to 5; and A is selected from the group consisting of a covalent bond, O, S, NH, and (CH 2 ) n where n is an integer from 1 to 3, with the proviso that when A is in the 4-position, R 1 is not bromine; with the proviso that when one of R 1 is bromine; and if A is in the 3- or 6-position, then bromine is in the 5-position, if A is in the 2- or 5-position, then bromine is in the 3-position, and when bromine is in the 3-position, and A is in the 2- or 5-position, then R 1 groups in the 4- and 6-positions are the same and are not bromine, chlorine or fluorine, and when bromine is in the 5-position, and A is in the 3- or 6-position, then R 1 groups in the 2- and 4-positions are the same and are not bromine, chlorine or fluorine; R 3 is selected from the group consisting of alkoxy, alkenyloxy, alkylthio and alkenylthio; and AC is an acyl protecting group; to form a compound of Formula (VII)
