One-Pot Multicomponent Synthesis of β-Acetamido Ketones Using BF3-Et2O as Catalyst
1 Department of Pharmaceutical Sciences, Singhania University, Jhujhunu-333515, Rajasthan, India. 2 National Institute of Pharmaceutical Education & Research, Raebareli229010, Uttar Pradesh, India. A b s t r a c t Starting from different ketones 1a-1f, aldehyde 2a-2g, and acetonitriles 3a-3d we synthesize some bioactive βAcetamido carbonyl compounds 4a-4h. We also attempted to synthesize these ...
متن کاملOne-Pot Synthesis of β-Acetamido Ketones Using Boric Acid at Room Temperature
β-acetamido ketones were synthesized in excellent yields through one-pot condensation reaction of aldehydes, acetophenones, acetyl chloride, and acetonitrile in the presence of boric acid as a solid heterogeneous catalyst at room temperature. It is the first successful report of boric acid that has been used as solid acid catalyst for the preparation of β-acetamido ketones. The remarkable advan...
متن کاملNano-TiO2: an Eco-friendly and Re-usable Catalyst for the One-pot Synthesis of β-Acetamido Ketones
β -Acetamido ketones are valuable building blocks for the preparation of β -amino ketones or β -amino alcohols such as the antibiotic nikkomycins [1] and neopolyoxines [2]. α-Acetamido ketones are obtained in the Dakin-West reaction [3] and β -acetamido ketones by the Iqbal route. In the latter, an aromatic aldehyde, an enolizable ketone and acetonitrile are condensed in the presence of acetyl ...
متن کاملEfficient synthesis of β’-amino-α,β-unsaturated ketones
A general and simple procedure to access chiral β'-amino-α,β-enones, in seven steps, from an α,β unsaturated ester has been described. The use of a Horner-Wadsworth-Emmons reaction as a key step for generating the β'-amino-α,β-enones, permits access to a range of substrates under mild conditions and in moderate to high yield.
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
