Syntheses of (R)-1,4,7,10-tetraoxaspiro[5.5]undecane (spirobi-1,4-dioxan), (R)-1,4,7-trioxa-10-thiaspiro[5.5]undecane, and (R)-1,4,7-trioxa-10-azaspiro[5.5]undecane from 2′-chloroethyl β-D-fructopyranoside are reported, in which the chirality of the spiro-ring junction is defined by the configuration of the anomeric carbon atom of the glycoside.
(R)-1,4,7,10-四氧杂螺[5.5]十一烷(spirobi-1,4-dioxan),(R -1,4,7-三氧杂-10-thiaspiro [5.5]十一烷的合成,以及报道了来自2'-氯乙基β - D-果糖吡喃糖苷的(R)-1,4,7-三氧杂-10-氮杂螺[5.5]十一烷,其中螺环连接的手性由异头异构体的构型定义糖苷的碳原子。
