Abstract
The amino acid catalyzed direct asymmetric Mannich reaction between aminomethyl ether 1 and cyclohexanones is presented. The unprecedented reaction proceeds via an ionic transition state and gives the corresponding Mannich bases in moderate to high yields with 75-99% ee.
Key words
organocatalysis - Mannich reactions - aminomethylation - amino acids - asymmetric catalysis
