Cubyl-caged systems: regiochemical steering of cationic rearrangements by distal groups

Novel carbonium ion rearrangements of substituted 1,3-bishomocubanones 3 & 4 to tricyclo(4.2.0.03,8)octane and bicyclo(3.2.1)octane ring systems are reported.

A synthetic entry into tetracyclo (4.2.0.02,4.03,8) octane system

Abstract Novel ceric ion oxidation of homocubanone provides a facile entry into tetracyclo(4.2.0.0 2,4 .0 3,8 )octane and tricyclo (3.3.0.0 2,7 )octane ring systems.

Cubyl caged systems: a paradigm of tandem cyclobutylcyclopropylcarbinyl carbonium ion rearrangements

A novel and general carbonium ion rearrangement of homocubanone to tetracyclo(3.3.0.02,8.03,6)octyl system is reported.

The deceptive rearrangement of a C8H9 cation of the cage type

We produce evidence to show that the acetolysis of exo-seco-cubyl mesylate gives 7-tetracyclo[3.3.0.02,8,03,6]octyl acetate as sole product and not 5-tetracyclo[4.2.0.02,403,8]-octyl acetate.

Cubanes uncaged: novel carbonium ion rearrangements of pentacyclo[4.3.0.02,5.03,8.04,7]nonan-9-ones (homocubanones) to bicyclo[3.2.1]octa-2,6-diene and tetracyclo[3.3.0.02,6.03,8]octane ring systems

Several new and unprecedented carbonium ion rearrangements of the cubyl system are reported.
