D-Ribose was converted into methyl 5-O-benzyl-beta-D-ribofuranoside and this, on tin-mediated allylation, gave a mixture of the 2-O-allyl and 3-O-allyl derivatives which were separated by chromatography. The more polar isomer was characterised as the 3-O-allyl derivative after conversion via 3-O-allyl-5-O-benzyl-1,2-O-isopropylidene-alpha-D-ribofuranose (which was also synthesised from 3-O-allyl-1
将D-核糖转化为甲基5-O-苄基-β-D-呋喃呋喃糖苷,并且在锡介导的烯丙基化中,得到2-O-烯丙基和3-O-烯丙基衍生物的混合物,将其通过色谱法分离。通过3-O-烯丙基-5-O-苄基-1,2-O-异亚丙基-α-D-呋喃核糖转化后,更具极性的异构体被表征为3-O-烯丙基衍生物(也由3- O-烯丙基-1,2-:5,6-二-O-异亚丙基-α-D-呋喃糖)成已知的5-O-苄基-1,2-O-异亚丙基-α-D-呋喃核糖。通过甲基2-O-烯丙基-5-O将3-O-烯丙基-5-O-苄基-β-D-呋喃呋喃糖苷转化为甲基2-O-烯丙基-5-O-苄基-β-D-核呋喃糖苷-苄基-3-O-(丙-1-烯)-β-D-呋喃呋喃糖苷。
