l-Fucopyranose and a couple of l-fucosidase inhibitors, 5-deoxy-5-thio-l-fucopyranose and 1,5-dideoxy-1,5-imino-l-fucitol, were prepared from a common pentose intermediate with α-d-arabino configuration. Stereoselectivities on carbon chain elongation of the key intermediate were successfully controlled by choosing the appropriate organometallic reagents.
l-岩藻吡喃糖以及几种l-岩藻苷酶抑制剂,5-脱氧-5-硫-l-岩藻吡喃糖和1,5-二脱氧-1,5-亚氨基-l-岩藻醇,均由具有α-d-阿拉伯糖构型的普通戊糖中间体制备而成。通过选择适当的金属有机试剂,成功控制了关键中间体碳链延伸的立体选择性。
