Disclosed is a method for mass-producing 4′-ethynyl d4T (4′-ethynyl-2′,3′-didehydro-3′-deoxythymidine) by a simpler process at low cost. Specifically disclosed is a method for producing 4′-ethynyl d4T, which is characterized by comprising a step for introducing a triple bond-containing group into a furfuryl alcohol derivative or a levoglucosenone, by reacting the furfuryl alcohol derivative or levoglucosenone with a certain compound, and a step for reacting a compound represented by the formula (III), which is obtained by the aforementioned step, with thymine.
本发明涉及一种以更简单低成本的方式大规模生产4'-乙炔基d4T(4'-乙炔基-2',3'-双脱氢-3'-脱氧胸腺嘧啶)的方法。具体揭示了一种生产4'-乙炔基d4T的方法,其特征在于包括以下步骤:通过将糠醇衍生物或乐禾葡萄糖酮与某种化合物反应,引入三键含有基团的步骤,反应产生式(III)所示的化合物,再与胸腺嘧啶反应。
