Reaction of 18 with potassium thiolbenzoate gave, after debenzoylation, oxidation, and deprotection, 6-(2,4-dichlorophenyl)-D-erythro-2,4-dihydroxyhexane-1-sulfonic acid (4). Reaction of 18 or 19 with triethyl phosphite gave, after deprotection, 6-(2,4-dichlorophenyl)-D-erythro-2,4-dihydroxyhexyl-phosphonic acid (5), and reaction of 19 with potassium cyanide gave, after subsequent hydrolysis and deprotection
由D-葡萄糖合成的6-(2,4-二氯苯基)-D-赤-1,2,4-己三醇被部分甲硅烷基化,然后与2-甲氧基丙烯反应,得到1-O-叔丁基二甲基甲硅烷基-6- (2,4-二氯苯基)-2,4-O-异亚丙基-D-赤-1,2,4-己三醇(17)。17的甲硅烷基化得到6-(2,4-二氯苯基)-2,4-O-异亚丙基-D-赤型-1,2,4-己三醇,将其转化为1-甲苯磺酸酯18和1-溴衍生物19在脱苯甲酰化,氧化和脱保护后,18与硫羟苯甲酸钾反应,得到6-(2,4-二氯苯基)-D-赤型-2,4-二羟基己烷-1-磺酸(4)。脱保护后,18或19与亚磷酸三乙酯反应,得到6-(2,4-二氯苯基)-D-赤型-2,4-二羟基己基膦酸(5),随后,19与氰化钾的反应得到水解和脱保护,7-(2,
