Data collection began in 2005 for the results of(More)
On the interaction of isocamphanone with butyllithium, 2-butyl-5,5,6-trimethylbicyclo[2.2.1]heptan-endo-2-ol is formed stereospecifically. As a result of skeletal rearrangements of carbonium ions taking place in the course of the reaction, the Ritter reaction of this tertiary alcohol with acetonitrile and benzonitrile has given(More)
The transformations of isofenchone and of 5-exo-ethylnorcamphor under the conditions of the Ritter reaction have been studied. These ketones undergo transformations similar to those that have been described for their structural analogues camphor and isocamphanone, as a result of which the corresponding geminal diamides are formed. The structures of the(More)
