, p. 2037 - 2045 (2015/12/24)
The C-C bond forming reactions are of fundamental importance in chemistry. As a result there is ever growing interest for chemists to develop new methods for C-C bond formation. We report here three dimensional nano-cage mesoporous aluminosilicate materia
NO cations as highly efficient catalysts for carbon-carbon bond forming reactions
Yamashita, Yasuhiro,Kobayashi, Shue
supporting information; scheme or table, p. 678 - 679 (2011/04/22)
NO cations were found to be a highly effective catalysts in several carbon-carbon bond forming reactions. For example, [3 + 2] cycloadditions of nitrones or azomethine imines with vinyl ethers proceeded in the presence of 0.1-1 mol % of the NO cation to afford the desired adducts in high yields.

An efficient synthesis of 3,4-dihydropyran-2-one derivatives by Lewis base-catalyzed tandem Michael addition and lactonization
Tozawa, Takashi,Fujisawa, Hidehiko,Mukaiyama, Teruaki
, p. 1454 - 1455 (2007/10/03)
A convenient one-pot preparation of 3,4-dihydropyran-2-one derivatives by Michael addition of silyl enolate derived from phenyl ester with α,β-unsaturated ketones in the presence of a Lewis base catalyst such as tetrabutylammonium phenoxide was developed. In this catalytic cycle, 3,4-dihydropyran-2-ones were produced in good to excellent yields via intramolecular cyclization of in situ formed Michael-adducts.
