Cooperative effect in organocatalytic intramolecular hydroamination of unfunctionalized olefins†
Abstract
The cooperative effect in organocatalytic hydroamination of unfunctionalized olefins was reported. In the presence of 3-hydroxy-2-naphthoic acid, N-benzyl 4-penten-1-amines and 5-hexen-1-amines produced the intramolecular cyclization products in good isolated yields.
