The borondipyrromethene (BODIPY) labeled new glycosylphosphatidylinositol (GPI) molecules were synthesized as cellular probes to study the chemical basis of microdomain organization of GPI-anchored proteins and cholesterol in plasma membrane. The synthesis enabled by a new stereo-selective glycosylation of myo-d-inositol acceptor led to the preparation of optically pure glucosaminyl-(1-6)-α-phosph

1-imidazoquinolinylalkanols. The resulting phosphite can be purified or directly oxidized with t-butyl hydroperoxide. The cyanoethyl protecting group is then removed with triethylamine and the phospholipidated imidazoquinoline products isolated in good yield and purity by simple filtration.
开发了一种高产且可扩展的亚磷酰胺工艺,用于 TLR7/8 活性咪唑并喹啉的磷脂化。该方法涉及1,2-二酰基-或二烷基-sn-甘油或3-氯甾醇与2-氰基乙基N , N , N ', N'-四异丙基亚磷二酰胺在1H-四唑存在下反应,然后用所得的N , N'-二异丙基亚磷酰胺脂质与 1-咪唑并喹啉基链烷醇原位反应。所得亚磷酸酯可以纯化或直接用叔丁基过氧化氢氧化。然后用三乙胺除去氰乙基保护基团,并通过简单的过滤以良好的产率和纯度分离磷脂化的咪唑喹啉产物。
