Tandem Reactions in Organic Synthesis: The Artistic Approach in Modern Organic Chemistry
(Universidad Militar Nueva Granada, 2016)
Synthesis of indole derivatives by domino hydroformylation/indolization of 2-nitrocinnamaldehydes
(ELSEVIER SCIENCE BV, 2008)
The present work furnishes an innovative preparation of substituted indoles based on tandem hydroformylation, where the chemo- and the regio-selectivities are good, so the yield of the reaction. The novelty has been ...
Comprehensive DFT study on site-, regio-, and stereoselectivity of diels-alder reactions leading to 5-hydroxybenzofurans
(Wiley VCH Verlag, 2011-02)
Diels-Alder reactions between the substituted furans 1a-1c and Danishefsky's diene (2), yielding 5-hydroxybenzofurans, were studied by density functional theory [B3LYP/6-31G(d) level] in benzene as solvent (SP/CPCM). The ...
Experimental and theoretical studies on polar Diels–Alder reactions of 1-nitronaphathalene developed in ionic liquids
(Royal Society of Chemistry, 2013)
The reactions between 1-nitronaphthalene 1 and two nucleophilic dienes, Danishefsky´s diene 2 and 1-trimethylsilyloxy-1,3-butadiene 3, to yield phenanthrenols 7 and 8 developed in protic and aprotic ionic liquids (ILs) ...
Microwave-Assisted Organocatalytic Intramolecular Knoevenagel/Hetero Diels–Alder Reaction with O -(Arylpropynyloxy)-Salicylaldehydes: Synthesis of Polycyclic Embelin Derivatives
(American Chemical Society, 2016-10)
highly efficient and regioselective approach to new polycyclic embelin derivatives through a domino Knoevenagel condensation/intramolecular hetero Diels−Alder reaction using O-(arylpropynyloxy)-salicylaldehydes in the ...
Synthesis of Biginelli adducts using a Preyssler heteropolyacid in silica matrix from biomass building block
(Elsevier Inc, 2018-12)
An efficient, suitable and high yielding method has been developed employing the use of the renewable platform molecule furfural for the synthesis of Biginelli derivatives via a three-component domino reaction through a ...
