Stereocontrolled radical reactions in carbohydrate and nucleoside chemistry.
摘要:
The radicals, generated by photolysis of 2,3-dimethyl ketals of N-hydroxy-2- thiopyridone uronic esters, reacted stereoselectively with electron deficient olefins leading to highly functionalised chain-elongated pentafuranosides, hexapyranosides and pentafuranosyl-nucleosides through the 4,5 and 4' radicals, respectively.
