Paragraph 0028-0029, (2020/07/13)
The invention discloses a visible light promoted method for constructing O-glycoside bonds. Glycosyl trichloroacetimidate is taken as a donor, and phenolic compounds are taken as a photocatalyst; a molecular sieve is added; and the O-glycoside bonds are g

The glycosylation reactions of glycosyl trichloroacetimidates and several alcohols using an organophotoacid as an activator under photoirradiation proceeded smoothly to give the corresponding glycosides in high yields. The organophotoacid was recovered and reused without any loss of efficiency. This journal is the Partner Organisations 2014.
Metallocene bis(perfluoroalkanesulfonate)s as air-stable cationic Lewis acids
Qiu, Renhua,Zhang, Guoping,Xu, Xinhua,Zou, Kangbin,Shao, Lingling,Fang, Dawei,Li, Yinhui,Orita, Akihiro,Saijo, Ryosuke,Mineyama, Hidetaka,Suenobu, Tomoyoshi,Fukuzumi, Shunichi,An, Delie,Otera, Junzo
experimental part, p. 1524 - 1528 (2009/09/06)
Zirconocene and titanocene bis(perfluorooctanesulfonate)s were synthesized. In contrast to the corresponding triflates and perchlorates, these compounds are air- and water-stable. They were proved to be ionic on the basis of conductivity measurements and X-ray analysis, allowing these complexes to be stored for months. The strong Lewis acidity of these cationic metallocene species, which was proved by ESR study, enabled catalytic glycosylation.
Environmentally benign β-stereoselective glycosidations of glycosyl phosphites using a reusable heterogeneous solid acid, montmorillonite K-10
