One-Pot Synthesis of Highly Substituted Allenylidene Derivatives via Palladium- or Nickel-Catalyzed Tandem Michael Addition,Cyclization Reaction

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 1-2 2009
Yun Shi
Abstract A simple and tandem synthetic approach, which offers an efficient, direct route to highly substituted indenes, has been developed by palladium- or nickel-catalyzed cyclization of propargylic compounds and nitrogen nucleophiles. The reaction takes place under mild conditions, and a possible mechansim is proposed. [source]

rac -9-Ethyl-12a-hydroxytetradecahydrotriphenylene-1,5(2H,4bH)-dione: stabilization of a new isomer of a functionalized perhydrotriphenylene through a tandem Michael addition,aldol reaction

ACTA CRYSTALLOGRAPHICA SECTION C, Issue 6 2008
Luis Arturo García
The title compound, C20H30O3, is a new functionalized perhydrotriphenylene derivative formed via a tandem Michael addition,aldol reaction. The structural study reveals that the system of fused rings approximates a C2 point symmetry, with trans,cis,cis ring junctions, while highly symmetric all- trans perhydrotriphenylene, previously characterized, approximates a D3 symmetry. The perhydrotriphenylene nucleus of the title compound corresponds to the third stable stereoisomer isolated for this polycyclic system. Considering that the Cs isomer was obtained recently through a similar tandem reaction, a general strategy is proposed which may help to obtain other stable stereoisomers of perhydrotriphenylene.
