aliphatic carboxylic acids with D2O as an inexpensive deuterium source. The use of Ph3P as an O‐atom transfer reagent can facilitate the deoxygenation of aromatic acids, while Ph2POEt is a better O‐atom transfer reagent for aliphatic acids. The highly precise deoxygenation of complex carboxylic acids makes this protocol promising for late‐stage deoxygenative deuteration of natural product derivatives
我们报告了从芳族和脂肪族羧酸与D 2 O作为廉价的氘源制备氘代醛的通用,实用和可扩展的方法。Ph 3 P作为O原子转移试剂的使用可以促进芳族酸的脱氧,而Ph 2 POEt是一种更好的脂族酸O原子转移试剂。复杂羧酸的高精度脱氧使该方案有望用于天然产物衍生物和药物化合物的后期脱氧氘代。
