One-step preparation of 6-perfluoroalkylalkanoates of trehalose and sucrose for biomedical uses
摘要:
The Mitsunobu reaction has been used to obtain 6-polyfluoroalkanoates of alpha,alpha-trehalose and sucrose in yields of approximately 40% and approximately 25%, respectively. 6,6'-Diesters (3-6%) were formed in some reactions and a 6-ester (1.3%) of alpha-D-glucopyranosyl 3,4-anhydro-beta-D-tagatofuranoside in one reaction. The monoesters displayed strong surfactant properties, and reduced considerably the water surface and fluorocarbon/water interfacial tensions. Preliminary results on biocompatibility were encouraging, especially for the 6-esters of alpha,alpha-trehalose.
