Michael addition of Pyrrole and indole to α,β- unsaturated compounds in the Presence of oxalic acid
A Simple and efficient method for Michael addition of pyrrole and indole to α,β- un saturated compounds has been developed in the presence of oxalic acid under refluxing reaction condition was achieved.
متن کاملSynthesis, Characterization and Fluorescence study of Certain Cinnamamide Derivatives and α, β unsaturated acids
A series of Cinnamamide were prepared by condensation of appropriate malonic acid derivatives with several aldehydes in presence of condensing agent and in its absence α, β Unsaturated acids were synthesized. The synthesized compounds were characterized by elemental analysis and I.R spectra. Introduction: Varley1 was the first to have used pyridine in malonic acid-aldehyde condensations. Later ...
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 کاملProcess for the synthesis of α, β-unsaturated esters
The present invention provides a process for the synthesis of an α,β-unsaturated ester from a mono-olefinester using Fe(CO).sub.5.
متن کاملOrganocatalytic asymmetric Michael-type reaction between β,γ-unsaturated α-keto ester and α-nitro ketone.
A Michael-type reaction of β,γ-unsaturated α-keto ester and α-nitro ketone was established. With a thiourea catalyst derived from cinchona alkaloid, the reactions afford products in 47-94% yields with 68-96% ee.
