Zinc-mediated alkylation and acylation of 1,3-dicarbonyl compounds
Yadav,Reddy, B. V. Subba,Mishra, Anand Kumar
experimental part, p. 280 - 281 (2010/09/05)
1,3-Dicarbonyl compounds undergo smooth allylation, benzylation, propargylation, and acylation with halides using metallic zinc in DMF at 60 °C to afford the corresponding allyl, benzyl, 2-propynyl, and acylated 1,3-diesters in good yields. In the case of cyclic 1,3-diketones, the corresponding enol ethers are obtained as sole products instead of C-alkylation.
Iron(III) tosylate in the preparation of dimethyl and diethyl acetals from ketones and β-keto enol ethers from cyclic β-diketones

An efficient method for conversion of ketones to their corresponding dimethyl and diethyl acetals and of cyclic β-diketones into β-keto enol ethers using Fe(OTs)3 as a catalyst is described. Copyright Taylor & Francis Group, LLC.
Formation of bicyclic pyrroles and furans through an enone allene photocycloaddition and fragmentation sequence
Lutteke, Ginger,Alhussainy, Rana,Wrigstedt, Pauli J.,Hue, B. T. Buu,De Gelder, Rene,Van Maarseveen, Jan H.,Hiemstra, Henk
experimental part, p. 925 - 933 (2009/04/04)
The [2+2] photocycloaddition of allenes 15-18, 23 and 26 was studied. Irradiation of a solution of these substrates in acetonitrile at 300 nm resulted in the clean conversion of the starting materials into a mixture of photoproducts. The major product in
Cerium(IV) ammonium nitrate-catalyzed synthesis of β-keto enol ethers from cyclic β-diketones and their deprotection
Banerjee, Biplab,Mandal, Samir Kumar,Roy, Subhas Chandra
, p. 16 - 17 (2007/10/03)
A mild and efficient method for etherification of cyclic β-diketones with alcohols has been developed using a catalytic amount of cerium(IV) ammonium nitrate at room temperature to afford the corresponding β-keto enol ethers in good to excellent yields. The deprotections of enol ethers in water-acetonitrile (1:1) using a catalytic amount (10 mol %) of cerium(IV) ammonium nitrate have also been achieved. Copyright
