experiments and condensation reactions with different thiophilic activatorsystems. It is revealed that the relative reactivity of the thioglycosides depends on the activatorsystem used and that p-nitrophenylsulfenyl triflate shows overall attenuated reactivity differences with respect to the commonly used N-iodosuccinimide/triflic acid promotersystem. With respect to the stereoselectivity of the studied galacturonic
