There can be provided an excellent industrial process for producing compounds having sugar-moiety hydroxyl groups or halogen atoms reduced in nucleic acids or in derivatives thereof by allowing O-thiocarbonyl derivatives of sugar-moiety hydroxyl groups or allowing halogenated derivatives in the sugar-moiety, in the nucleic acids or in derivatives thereof to react with any one of hypophosphorous acids (including salts thereof) and phosphites (esters) which are inexpensive, non-toxic and safely usable as radical reducing agents in industrial scale, in the presence of a radical reaction initiator.
The process of the present invention is an industrially useful and highly safe process for reducing sugar-moiety hydroxyl groups and halogen atoms in nucleic acids or derivatives thereof (including nucleic acid-related compounds) at low costs.
