The reagent chloro-β-cyanoethyl-N,N-diisopropylamino-phosphoramidite reacts smoothly with the anomeric hydroxyl group of a properly protected (benzyl) α-L-fucopyranose to afford a relatively stable phosphite intermediate in high yield. The latter can easily be converted into valuable α-L-fucopyranosyl phosphoric mono- and diesters.
氯-β-氰基乙基-N,N-二异丙基氨基-亚磷酰胺试剂与适当保护的(苄基)α-L-呋喃二糖的异头羟基平滑反应,以高收率提供相对稳定的亚磷酸酯中间体。后者可以容易地转化为有价值的α-L-呋喃核糖基磷酸单酯和二酯。
