The invention provides a process for producing a β-dihydrofuran derivative represented by formula (1) or a β-tetrahydrofuran derivative represented by formula (4), characterized in that the process includes causing a dialkyl dicarbonate, a diaralkyl dicarbonate, or a halide to act on a diol compound represented by formula (2) or (3). The invention also provides a process for producing 4′-ethynyl-2′,3′-didehydro-3′-deoxythymidine or an analog thereof, the process including glycosylation and deprotection.

uncommon yet useful compounds. Rarer still are examples of PBGs that are active at visible wavelengths. We report the synthesis and characterization of new photolabile amine protecting groups that are active under visible light. The new chromophore, benzothiophene imino-phenylacetonitrile (BTIPA), was synthesized in four steps without use of chromatography and found to release any one of several amines
