A photoinduced electron-transfer (PET) reaction was used for the deoxygenation at C-2 of aldonolactones derivatized as 2-O-[3-(trifluoromethyl)benzoyl] or benzoyl esters. By irradiation of different D-galactono- and D-glucono-1,4-derivatives, with a 450W lamp, using 9-methylcarbazole as photosensitizer, the corresponding 2-deoxy-D-lyxo- and 2-deoxy-D-arabino-hexono-1,4-lactones were efficiently obtained.
光诱导电子转移（PET）反应被用于对衍生为2-O-[3-(三氟甲基)苯甲酰基]酯或苯甲酰酯的醛糖内酯的C-2位进行脱氧反应。通过用450W灯照射不同的D-半乳糖-1,4-衍生物和D-葡萄糖-1,4-衍生物，以9-甲基咔唑作为光敏剂，有效地得到了相应的2-脱氧-D-来苏糖-1,4-内酯和2-脱氧-D-阿拉伯糖-己糖-1,4-内酯。
