Preparing methods of ipragliflozin intermediates

The invention discloses preparing methods of ipragliflozin intermediates. The methods includes preparing methods for 2-(3-benzo[B]thien-2-ylmethyl-4-fluorophenyl)-3,4,5-tris(trimethylsiloxy)-6-trimethylsiloxymethyl-tetrahydro-pyran-2-ol (a compound 3) and (1S)-2,3,4,6-tetraacetoxy-1,5-anhydro-1-[3-(1-benzothiophen-2-yl-methyl)-4-fluorophenyl]-D-glucitol (a compound 6). Under the premise of controlling the temperature of a reaction solution to be not higher than -60 DEG C, n-butyllithium should be added dropwise as soon as possible, and the higher the adding speed of the n-butyllithium is, theless F-ortho-position substituted side products of the compound 3 are, thus ensuring purity of the compound 3 and directly influencing the yield of the compound 6 finally prepared. Through scale-up, the methods are free of scale-up effects, and are suitable for industrial production.

METHOD FOR PRODUCING C-GLYCOSIDE DERIVATIVE AND SYNTHETIC INTERMEDIATE THEREOF

The present invention provides a method for producing a C-glycoside derivative, which can produce the C-glycoside derivative at a high yield and at a low cost, which conforms to environmental protection, and which is applicable industrially. The C-glycoside derivative is useful for treating and preventing diabetes such as insulin-dependent diabetes (type 1 diabetes), non-insulin-dependent diabetes (type 2 diabetes) and the like and various diabetes-related diseases including insulin-resistant diseases and obesity.
