Iodine: A Versatile Reagent in Carbohydrate Chemistry. Part 3. Efficient Activation of Glycosyl Halides in Combination with DDQ. -Iodine, alone or in combination with DDQ, efficiently activates glycosyl halides for the reaction with alcohols to yield 1,2-trans-glycosides. Even sub-stoichiometric qua
Iodine, either alone or in combination with DDQ, has been found to serve as a very efficient reagent for the conversion of 'disarmed' glycosyl halides into simple 1,2-trans-glycosides. This reagent system represents a practical alternative to traditional heavy metal promoters in glycoside synthesis.
