|4. APPLICATION||- Used as general industrial ﬁne chemical.
- Used as organic soluble source of Pyridium ion.
- It is intermediate of Tacrolimus and Orlistat Immunosuppressant, anti-obesity/pancreatic lipase inhibitor.
In organic synthesis, PPTS is used as a weakly acidic catalyst, providing an organic soluble source of pyridinium (C5H5NH+) ions. For example, PPTS is used to deprotect silyl ethers or tetrahydropyranyl ethers when a substrate is unstable to stronger acid catalysts.
- It is also a commonly used catalyst for the preparation of acetals and ketals from aldehydes and ketones.
- As a co-catalyst with L-proline improved both yield and enantioselectivity of an asymmetric aldol condensation between dioxanones and aldehydes.
