An environmentally friendly oxidative cleavage of tetrahydrofuran‐2‐methanols to the corresponding γ‐lactones using a catalytic amount of 2‐iodo‐N‐isopropylbenzamide has been developed. The reaction of various tetrahydrofuran‐2‐methanols with the catalyst in the presence of Oxone® (2 KHSO5⋅KHSO4⋅K2SO4) as a co‐oxidant in DMF at room temperature successfully affords the corresponding lactones in good
已开发出使用催化量的2-碘-N-异丙基苯甲酰胺对四氢呋喃-2-甲醇进行环境友好的氧化裂解为相应的γ-内酯。各种四氢呋喃-2-基甲醇与催化剂在存在反应的Oxone ®(2 KHSO 5 ⋅KHSO 4 ⋅K 2 SO 4),其在室温下共氧化剂在DMF成功得到良好的相应的内酯,以高收率,并通过还原后处理即可轻松实现催化剂的回收。该方法之所以显着,是因为它可以在温和的条件下将四氢呋喃-2-甲醇转化为γ-内酯,而无需使用任何有毒的重金属。
