Neodymium(III)-mediated reformatsky-type reactions of α-halo ketones with carbonyl compounds

In a neodymium(III) iodide induced process, α-bromo ketones 1 and aldehydes 2 are effectively converted into aldol products 3. This Reformatsky-type reaction proceeds through the formation of a neodymium enolate at room temperature in CH2Cl2. The analogous reaction in the presence of NdBr3/NaI at 50°C in THF favors the formation of corresponding aldol-Tishchenko products 5 in good yields. Studies to define the scope and limitations of these reactions mediated by neodymium(III) salts are also described. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
Synthesis and acid- or base-catalyzed cyclization of various 4-pentyne-1,3-dione derivatives

4-Pentyne-1,3-dione derivatives having various substituents were conveniently synthesized from ynals and silyl enol ethers in two steps. The cyclization behaviors of the obtained 4-pentyne-1,3-diones were studied. γ-Pyrones and 3(2H)-furanones were obtain
