Use of glycerol, waste glycerol from biodiesel production and other protic solvents in bioactive α,β-unsaturated ketones synthesis
(2020-06-01)
Glycerol is the main co-product from biodiesel production and has been recognized as a sustainable solvent. Herein, we used glycerol and waste glycerol in synthesis of two bioactive α,β-unsaturated ketones (E,E)-1,5-diph ...
Synthesis of Phenanthrenol Derivatives Through Polar Diels-Alder Reactions Employing Nitronaphthalenes and (E)-1-(Trimethylsilyloxy)-1,3- butadiene. Theoretical Calculations
(Bentham Science Publishers, 2014-02)
The cycloaddition reactions between nitronaphthalenes and 1-trimethylsilyloxy-1,3-butadiene produce phenantrenol derivatives as principal products. The primary adducts suffer the irreversible lost of nitrous acid and ...
Remarkable reactivity of boron-substituted furans in the Diels-Alder reactions with maleic anhydride
(American Chemical Society, 2019-06-19)
The reactivity of boron-substituted furans as dienes in the Diels-Alder reaction with maleic anhydride has been investigated. Gratifyingly, the furans with boryl substituents at C-3 gave the exo cycloadduct exclusively ...
Asymmetric Organocatalytic C-C Bond Forming Reactions with Organoboron Compounds: A Mechanistic Survey
(Wiley VCH Verlag, 2019-05-26)
The recent development of asymmetric organocatalytic C-C bond forming reactions involving organoboranes has attracted big interest in the synthetic community. Asymmetric organocatalytic additions to enones, aldehydes, ...
Understanding the Role of Protic Ionic Liquids (PILs) in Reactive Systems: Rational Selection of PILs for the Design of Green Synthesis Strategies for Allylic Amines and β‐Amino Esters
(Wiley-VCH Verlag, 2019-07)
The reactive behaviour of protic ionic liquids (PILs) has been shown to be governed not only by their chemical structures but also by their global compositions, which include the presence of free acids and bases at equilibrium ...
Synthesis of 2H-naphtho[2,3-b]thiopyranoquinones and density functional study for the Diels-Alder reaction of a benzothiopyranoquinone
(PERGAMON-ELSEVIER SCIENCE LTD, 2000)
The synthesis of benzothiopyranoquinone (6) in three step from benzothiopyran (3) is described. Diels-Alder reaction of quinone (6) with 1,3-pentadiene (7), cyclopentadiene, 1-methoxy-1,3-cyclohexadiene (11) and ...
A regioquímica das reações de Diels-Alder de N-tosil para-benzoquinona iminas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2012-02-29)
In this work it was done a comparative study on the reactivity of a variety of dienophiles including para-benzoquinones, their mono-oximes, their N-tosyl mono-oximes and their N-tosylimines on the Diels-Alder reactions ...
