A simple one-pot procedure to obtain a series of five- and six-membered heterocycles, in three different ionic liquids ([BMIM][BF4], [BMIM][OH] and [HMIM][HSO4]) is described. The synthetic protocol involves the reaction between β-en

Condensation of aromatic acyl compounds with N,N-dimethylformamide diethyl acetal in a pressure tube under microwave heating gives 1-aryl-3-dimethylaminoprop-2-enones in almost quantitative yields. In the presence of hydrazine, these intermediates are transferred to the corresponding 3-arylpyrazoles.
