2-O-(3-trifluoromethyl)benzoylated derivative of d-galacturonic acid. The carboxylic group efficiently assists α-deoxygenation, the required irradiation time being significantly shorter than that in the absence of it. The photochemical reaction was also used for the deoxygenation of d-glucurono-6,3-lactone derivatives, providing in both cases the convenient routes for the synthesis of 5-deoxy-hexofuranosides
随着合成脱氧糖的实用方法的发展,将以9-甲基咔唑(MCZ)为光敏剂的光致电子转移(PET)反应应用于d的2- O-(3-三氟甲基)苯甲酰化衍生物。 -半乳糖醛酸。羧基有效地辅助了α-脱氧,所需的照射时间明显短于不存在时的照射时间。光化学反应还用于d-葡萄糖醛酸-6,3-内酯衍生物的脱氧,在两种情况下均提供了合成5-deoxy-六呋喃糖苷和中间体化合物以合成天然产物的便捷途径,避免了使用金属氢化物。
