There is provided a production method of a compound represented by the following formula (II) through a step of reacting a compound represented by the following General Formula (I) with a sulfur compound.
In General Formulas (I) and (II), R1 represents a hydrogen atom or an acyl group, R2 represents a hydrogen atom, a fluorine atom, an acyloxy group, an arylmethyloxy group, an allyloxy group, an arylmethyloxycarbonyloxy group, or an allyloxycarbonyloxy group, R3 represents a hydrogen atom or an acyloxy group, R5 represents an alkyl group or an aryl group, and X represents a leaving group.
Here, in a case where R2 is a fluorine atom, an acyloxy group, an arylmethyloxy group, an allyloxy group, an arylmethyloxycarbonyloxy group, or an allyloxycarbonyloxy group, R3 is an acyloxy group.
本发明提供了一种下式(II)化合物的生产方法,其步骤是将下式(I)化合物与硫化合物反应。
在通式(I)和(II)中,R1 代表氢原子或酰基,R2 代表氢原子、氟原子、酰氧基、芳基甲基氧基、烯丙基氧基、芳基甲基氧基羰基氧基或烯丙基氧基羰基氧基,R3 代表氢原子或酰氧基,R5 代表烷基或芳基,X 代表离去基团。
这里,在 R2 是氟原子、酰氧基、芳基甲基氧基、烯丙基氧基、芳基甲基氧基羰基氧基或烯丙基氧基羰基氧基的情况下,R3 是酰氧基。
