The invention relates to a C-
aryl glucoside derivative, as well as a medical composition, a preparation method and application thereof. The preparation method comprises the following steps of: method I, in a
solvent, under the action of alkali, performing a deacetylation
protecting group reaction on compounds 1-f; method II: 1, performing a
Mitsunobu reaction on components 2-g and (as shown in the description); and 2, performing a deacetylation
protecting group reaction on the compounds 2-f obtained in the step 1; and method III: 1, mixing compounds 3-g and (as shown in the description), and performing a
nucleophilic substitution reaction; and 2, performing a deacetylation
protecting group reaction on the compounds 3-f obtained in the step 1. The medical composition comprises the C-
aryl glucoside derivative, salt and / or
prodrug of the C-
aryl glucoside derivative which are / is acceptable in
pharmacy, and auxiliary materials. The invention further relates to the C- aryl glucoside derivative, and application of salt or medical compositions of the C- aryl glucoside derivative, which is acceptable in
pharmacy, for preparing
SGLT inhibitors. The C- aryl glucoside derivative disclosed by the invention provides a new direction for research of the
SGLT inhibitors. (As shown in the description)
