Novel cis-1,2-fused 1,3-oxathiolan-, 1,3-oxaselenolan-, and 1,3-oxazolidin-2-imine carbohydrate derivatives have been prepared by treatment of the corresponding 1,2-anhydrosugars with potassium thiocyanate, potassium selenocyanate, and sodium cyanamide, respectively. The procedure is compatible with several protecting groups such as acyl, benzyl, and silyl and also with sugars of different configurations
通过用硫氰酸钾处理相应的1,2-脱水糖,制备了新的顺式1,2-稠合的1,3-氧杂硫杂环戊烷,1,3-氧杂壬醇和1,3-恶唑烷-2-亚胺碳水化合物衍生物,硒氰酸钾和氰胺钠。该方法与几种保护基如酰基,苄基和甲硅烷基以及与不同构型的糖相容。
