Abstract The four 5,6-dideoxy-6-halogeno-1,2- O -isopropylidene-3- O -methyl-α- d - xylo -hept-5-eno-1,4-furanurononitriles (bromo, chloro, fluoro, and iodo) were prepared by treatment of 1,2- O -isopropylidene-3- O -methyl-α- d -pentodialdo-1,4-furanose with the corresponding (cyanohalogenomethylene)triphenylphosphorane. The geometrical isomers were separated by liquid chromatography. Spectral data
摘要四个5,6-二脱氧-6-卤代-1,2-O-异亚丙基-3-O-甲基-α-d-二甲苯基-庚基-5-eno-1,4-呋喃呋喃腈(溴,氯,氟通过用相应的(氰基卤代亚甲基)三苯基膦处理1,2-O-异亚丙基-3-O-甲基-α-d-戊二醛-1,4-呋喃糖来制备。通过液相色谱分离几何异构体。四个腈和相应的烯腈的光谱数据用于鉴定构型和构象。
