설명

애플리케이션

• Sulfation agent

Reactant for:

• Preparation of azido anologs of pregnanolone
• Sulfate esters of morphine derivatives
• Gold nanoparticles capped with sulfate-ended ligands as anti-HIV agents

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.
As a sulfating agent, SO₃-py complex can be used for the preparation of sulfated-chitins, sulfated hyaluronan (HyaS) derivatives and sulfated starch.
