INTERMEDIATE FOR SYNTHESIS OF 1-(2-DEOXY-2-FLUORO-4-THIO-β-D-ARA BINOFURANOSYL) CYTOSINE, INTERMEDIATE FOR SYNTHESIS OF THIONUCLEOSIDE, AND METHODS FOR PRODUCING THESE INTERMEDIATES.

摘要

A compound represented by general formula [1D] (in the formula, R1A, R1B, R2A, R2B, R3A and R3B each denote a hydrogen atom, an optionally substituted C1-6 alkyl group, and the like) is useful as an intermediate for producing a thionucleoside, and this production method is useful as a method for producing a thionucleoside.
