Few methods allow for the direct conversion of cycloalkenes into cycloalkadienes with high chemo- and regioselectivity. Herein, we report a convenient one-pot process for this transformation that involves the unprecedented N-preferential group transfer of N-oxoammonium salts to cycloalkenes, followed by Cope elimination, to afford cycloalkadienes at room temperature and pressure.
Regioselective rhodium-catalyzed allylic alkylation/ring-closing metathesis approach to carbocycles
Evans,Kennedy, Lawrence J.

Treatment of the allylic carbonates 1a-c with the sodium anion of the α-substituted malonates (n = 0-2) and Wilkinson's catalyst modified with a triorganophosphite, furnished the allylic alkylation products 2/3a-i in 83-97% yield, favoring 2a-i. The diene
