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 endo-3-butyl-1,7,7-trimethylbicyclo[2.2.1]hept-exo-2-ylacylamines and endo-6-butyl-1
在异莰酮与丁基锂的相互作用下,2-丁基-5,5,6-三甲基双环[2.2.1]庚烷-内-2-醇立体定向地形成。由于在反应过程中发生碳正离子的骨架重排,该叔醇与乙腈和苄腈的里特反应得到了内-3-丁基-1,7,7-三甲基双环[2.2.1]庚-exo-2-ylacyamines 和endo-6-丁基-1,7,7-trimethylbicyclo[2.2.1]hept-2-ylacyamines。
