Borane-mediated deoxyfluorination of in situ generated N-H-O-alkyl-isoureas using Et3N ⋅ 3HF represents a novel approach to achieve a highly 2°-alcohol-selective substitution in preference to benzylic, 1° and 3° alcohol deoxyfluorination. The key to the 2° selectivity is the relative stability of the N-BBN-O-alkyl-isoureas towards elimination of the carbodiimide.

硼烷介导的醇类高度二级选择性脱氧氟化反应



使用 Et3N ⋅ 3HF 对原位生成的 NH-O-烷基异脲进行硼烷介导的脱氧氟化代表了一种优先于苄基、1° 和 3° 醇脱氧氟化实现高度 2°-醇选择性取代的新方法。2° 选择性的关键是 N-BBN-O-烷基异脲对消除碳二亚胺的相对稳定性。
