Diels-Alder reactions in pyridinium based ionic liquids
Xiao, Ying,Malhotra, Sanjay V.
, p. 8339 - 8342 (2004)
Diels-Alder reactions have been investigated in pyridinium based ionic liquids. These solvents are found to be more effective compared to the organic solvent studied, in enhancing the reaction rate and product yields. Recycled ionic liquids also gave exce

First Synthesis of rac-Homofenchone (1,4,4-Trimethylbicyclooctan-3-one)

The rac-homofenchone (2), which was previously unknown, is prepared starting from the cyclohexenecarboxylate 4 via the bicyclooctene 13 by two independent routes.The key steps are either the intramolecular acylation of a C=C bond in 9 induced by trifluoroacetic acid anhydride, or the BF3-catalyzed decomposition of the diazomethyl ketone 15.From 13 a direct path leads to homofenchone (2), the NMR spectra of which were fully assigned.
