Stereoselective Alkylation of Chiral Titanium(IV) Enolates with tert-Butyl Peresters
(American Chemical Society, 2021-11-19)
[EN]Here, we present a new stereoselective alkylation of titanium(IV) enolates of chiral N-acyl oxazolidinones with tert-butyl peresters from Calpha-branched aliphatic carboxylic acids, which proceeds through the decarboxylation ...
Unprecedented Multicomponent Organocatalytic Synthesis of Propargylic Esters via CO2 Activation
(Wiley‐VCH, 2019-02-19)
An efficient and straightforward organocatalytic method for the
direct, multicomponent carboxylation of terminal alkynes with
CO2 and organochlorides, towards propargylic esters, is reported
for the first time. ...
Manganese-Catalyzed Multicomponent Synthesis of Tetrasubstituted Propargylamines: System Development and Theoretical Study
(Wiley-VCH, 2020-07-20)
The importance of multicomponent reactions as an efficient tool in organic synthesis is widely recognized, as the need for sustainable, practical, atom- and step-economic methodologies is becoming a crucial concept in ...
Reduced Graphene Oxide/Polymer Monolithic Materials for Selective CO2 Capture
(MDPI, 2020-04-17)
Polymer composite materials with hierarchical porous structure have been advancing in many different application fields due to excellent physico-chemical properties. However, their synthesis continues to be a highly ...
An umpolung strategy to react catalytic enols with nucleophiles
(Nature, 2019-11-20)
The selective synthesis of a-functionalized ketones with two similar enolizable positions can be accomplished using allylic alcohols and iridium(III) catalysts. A formal 1,3-hydrogen shift on allylic alcohols generates ...
Computational understanding of heterocyclisation reactions and synthesis of fluorinated isoquinolines
(2020-11-27)
The present thesis deals with three different topics that have in common the formation of carbo- and heterocycles. The whole work is organized as a synergy of experimental and computational studies to provide a deep ...
Stereoselective, Ruthenium-Photocatalyzed Synthesis of 1,2-Diaminotruxinic Bis-amino Acids from 4-Arylidene-5(4H)-oxazolones
(American Chemical Society, 2022-02-10)
[EN] The irradiation of (Z)-2-phenyl-4-aryliden-5(4H)-oxazolones 1 in deoxygenated CH2Cl2 at 25 °C with blue light (465 nm) in the presence of [Ru(bpy)3](BF4)2 (5% mole ratio) as a triplet photocatalyst promotes the [2+2] ...
Multicomponent Catalytic Reactions: Theoretical and Experimental Studies
(2021-09-28)
In this thesis, Density Functional Theory (DFT) methods have been applied to study the mechanisms of three different multicomponent organic reactions. Also, a new synthetic procedure for the preparation of quinolinium salts ...
Selective C(sp2)−H Halogenation of "click" 4-Aryl-1,2,3-triazoles
(American Chemical Society, 2017-02-09)
Selective bromination reactions of “click compounds” are described. Electron-neutral and electron-deficient arenes selectively undergo unprecedented Pd-catalyzed C–H ortho-halogenations assisted by simple triazoles as ...
A computational glance at organometallic cyclizations and coupling reactions
(2016-07-18)
Organometallic chemistry is one of the main research topics in chemical science.Nowadays, organometallic reactions are the subject of intensive theoretical investigations.However, in many cases, only joint experimental and ...
