A catalytic formal ene reaction between ketone-derived silyl enol ethers and terminal alkynes is described. This transformation is uniquely capable of bimolecular assembly of 2-siloxy-1,4-dienes and can be used to access β,?-unsaturated ketones containing quaternary carbons in the α-position.
Cyclialkylation of arylalkyl epoxides with solid acid catalysts
Elings, Jacob A.,Downing, Roger S.,Sheldon, Roger A.
, p. 837 - 846 (2007/10/03)
Solid acids, such as zeolites and clays, catalyse the intramolecular hydroxyalkylation (cyclialkylation) of several arylalkyl epoxides in moderate to excellent conversions and selectivities. The use of solid acids in these cyclialkylations provides a cleaner, better alternative to conventional Lewis and Bronsted acids, enabling a more facile workup of reaction mixtures and, in several cases, better selectivities.
