Sulfur trioxide-pyridine (SO3-py) complex can be used to convert the allylic or benzylic hydroxyl group of compounds such as geraniol, farnesol, and 1-indanol into sulfate monoester, which is a good leaving group. This method is highly useful in the total synthesis of sesquiterpenes.[1]
As a sulfating agent, SO3-py complex can be used for the preparation of sulfated-chitins[2], sulfated hyaluronan (HyaS) derivatives[3] and sulfated starch.[4]
