Doing the two step: A very simple two-step access to polysubstituted cyclopentenones from terminal alkynes, [M(CO)6], and bromoalkenes is described. This protocol is an alternative to the intermolecular Pauson-Khand reaction, and can be used wi
Rearrangement of 1-(1-alkynyl)cyclopropanols to 2-cyclopentenones via their hexacarbonyldicobalt complexes. A new use of alkyne-CO2(CO)6 complexes in organic synthesis

A novel rearrangement of 1-(1-alkynyl)cyclopropanols to 2-cyclopenten- 1-ones proceeded on complexation of their alkynyl part with octacarbonyldicobalt (Co2(CO8)). 1-(1-Alkynyl)cyclopropanols with a wide range of substituents on thei
A Conformationally Controlled Regioselective of 2-Substituted 1-Alkynylcyclopropanols to 2-Cyclopenten-1-ones via Hexacarbonyldicobalt Complex
Iwasawa, Nobuharu,Iwamoto, Mari
, p. 1257 - 1260 (2007/10/02)
The rearrangement of hexacarbonyldicobalt-complexed 2-substituted 1-alkynylcyclopropanol derivatives is conformationally controlled to give 3- or 5-substituted 2-cyclopentanones regioselectively.In the cases of the reactions of 2-monosubstituted 1-alkynyl
DIASTEREOSELECTION IN RHODIUM-MEDIATED INTRAMOLECULAR C-H INSERTION: PREPARATION OF A TRANS-3,4 DIALKYL CYCLOPENTANE
Taber, Douglass F.,Ruckle, Robert E.
, p. 3059 - 3062 (2007/10/02)
Transition state analysis suggests that substantial 1,2 asymmetric induction could be observed in the course of rhodium-mediated intramolecular C-H insertion.This analysis succesfully predicts predominant formation of the trans 3,4-dialkyl cyclopentane wh
