Highly enantioselective intramolecular Michael reactions by D-camphor-derived triazolium salts.
Camphor-derived chiral triazolium salts have been found to be highly efficient for asymmetric intramolecular Michael reactions. With 1-5 mol% of the catalyst, the desired products were obtained in excellent yields, with up to 99% ee.
