The glycosylations of glycals and alcohols using N-iodosuccinimide (NIS) and a catalytic amount of PPh3 effectively proceeded under mild conditions to provide the corresponding 2-deoxy-2-iodoglycosides in high yields. The reactivity of the iodoglycosylations with PPh3 significantly increased in comparison to that using NIS alone as an activator. In addition, the glycosylations of glycals and alcohols using catalytic amounts of NIS and P(OPh)3 were effectively realized to give the corresponding 2-deoxyglycosides in high yields.
