[Rh(CO)2Cl]2-Catalyzed Domino Reactions Involving Allylic Substitution and
Carbocyclization Reactions. — Rhodium-catalyzed cascade reactions
37- 061 Subsequent
of α-substituted sodiomalonates with a variety of allylic trifluoroacetates are reported.
The experimental procedure is operationally simple as only a change in temperature is
necessary to promote the second step of the overall transformation. Starting with a regio- and stereoselective allylic alkylation, three different carbocyclizations including
intramolecular Pauson—Khan reaction, an enyne cycloisomerization, and a [5 + 2] cycloaddition are performed subsequently. — (ASHFELD, B. L.; MILLER, K. A.;
