The endo- and exo-1,7,7-Trimethylbicyclo[2.2.1]heptan-2-amines (Bornan-2-amines) and their acetamides

Abstract

Melting points provide a poor method for differentiation between the exo and endo N-(bornan-2-yl)- acetamides, and have led to errors by previous workers. Spectral differences leading to unambiguous assignment are discussed in this paper. Trapping of the bornan-2-yl carbenium ion with acetonitrile leads to exo products.
