General description

Camphorsulfonic acid is a organosulphur compound.

Application

Camphor-10-sulfonic acid (β) (CSA) is extensively used as an acid catalyst.
  • It can be used in a catalytic amount to protect hydroxyl groups as tetrahydropyranyl (THP) ethers using dihydropyran.
  • It also catalyzes the protection of ketones as ketals.
  • It is a useful catalyst for the intramolecular ring opening of epoxides.
  • CSA can also be used to catalyze nucleophile-promoted alkyne-iminium cyclization in the total synthesis of pumiliotoxin A.
