approach for the synthesis of 1,2,3,5-tetraacetylcarba-alpha-D-lyxofuranose from D-ribose is reported via one-pot conversion of to using Tebbe reagent which involves a cascade reaction sequence of methylenation, cleavage of isopropyl group, carbocyclization and again methylenation.
通过Tebbe试剂的一锅法转换,涉及一种由D-核糖合成1,2,3,5-四乙酰基氨基甲酸-α-D-呋喃糖的新的,高效的和非对映选择性的方法,涉及级联反应顺序为甲基化,异丙基裂解,碳环化和再次甲基化。
