The Girard’s reagent, which gives water-soluble derivatives of carbonyl compounds, was used together with silica gel as a protective reagent of them in a non-aqueous solvent system. Less hindered or more reactive carbonyl compounds were selectively protected by this method in competitive reductions.
Girard's 试剂产生羰基化合物的水溶性衍生物,与硅胶一起用作它们在非水溶剂系统中的保护试剂。通过这种方法在竞争性还原中选择性地保护了较少受阻或更具反应性的羰基化合物。
