A novel skeletal rearrangement in the Ritter reaction was examined which conveniently generated p-menthane diamides from turpentine. A probable reaction mechanism was proposed based on employing thermodynamic analysis. All the products were purified and characterised by1H NMR, IR, X-ray crystallography and ESI+-MS.

p-Menth-3-en-1-amine, 4, and its Schiff base derivatives, 5a-l, were designed and synthesized. They were characterized by FT-IR, ESI+-MS, HRMS, 1H NMR, and 13C NMR spectral analyses, and their pre-emergence herbicidal activities against ryegrass were evaluated. All of the compounds showed excellent herbicidal activity. The Schiff bases showed stronger herbicidal activities than the original amine 4. These compounds showed herbicidal activities comparable to that of glyphosate. The herbicidal activities of 5k and 5l against ryegrass shoot growth were 78.3 and 355.6% higher than that of glyphosate, respectively. Furthermore, the introduction of a chlorine or bromine atom into the Schiff base derivatives containing a furan or benzene ring was beneficial to increase the activity. However, the herbicidal activities were not clearly affected when the heteroatom of the five-membered heterocyclic Schiff base or the position of the substituent on pyridine Schiff base was altered.

It has been shown that the interaction of terpin hydrate with various nitriles under the conditions of the Ritter reaction takes place stereoselectively and leads to the formation of a mixture of isomeric cis- and trans-N,N'-diacyl-p-menthane-1,8-diamines in a ratio of 1:4.The structures of the products have been shown by 1H and 13C spectroscopy.
