oxidised to produce a high-value compound in high yield using a NaOtBu-O2 system. Furthermore, the synthetic utility of the resulting product was demonstrated by its transformation into unnatural α-amino acids, thus showing the valorisation of glycerol biomass.
甘油衍生物是一类重要的化合物,作为有机合成中的基本结构基石具有很大的应用前景。使用NaO t Bu-O 2系统将O-苄基甘油氧化以高收率生产高价值的化合物。此外,通过将其转化为非天然的α-氨基酸证明了所得产物的合成效用,从而表明了甘油生物质的增值。
