Abstract: | The solvolytic fragmentation of cis- and of trans-3-amino-cyclohexyl p-toluenesulfonates 8a and 9a and the corresponding N, N-dimethyl derivatives 8b and 9b has been studied. In 80% ethanol the cis-amino-tosylates 8a and 8b react faster than the homomorphous cis-3-alkyl-cyclohexyl tosylates 11a and 11b to yield fragmentation product exclusively or predominantly. The synchronous mechanism predictable on stereoelectronic grounds is therefore indicated. |
