The endo- and exo-1,7,7-Trimethylbicyclo-heptan-2-amines (Bornan-2-amines) and Their Acetamides

Carman, Raymond M.,Greenfield, Kay L.

, p. 1785 - 1790 (2007/10/02)

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.
