Data Analysis in Chemistry and Bio-Medical Sciences
(MDPI, 2016-12-14)
There is an increasing necessity for multidisciplinary collaborations in molecular science between experimentalists and theoretical scientists, as well as among theoretical scientists from different fields. One of the more ...
Naphthyl-Containing Organophosphonate Derivatives of Keggin-Type Polyoxotungstates
(MDPI, 2016-06)
New organophosphonate derivatives of monovacant Keggin-type polyoxotungstates that contain naphthyl groups have been synthesized and characterized in both solid state and solution. Single-crystal structural analysis shows ...
Mechanistic Insights in the Mode of Action of Bifunctional Pyrrolidine-Squaramide-derived Organocatalysts
(Wiley-VCH, 2016)
The modes of catalytic action of three squaramide-derived
bifunctional organocatalysts have been investigated using DFT
methods. The [5+2] cycloaddition between oxidopyrilium ylides and
enals has been used as model ...
Organocatalytically Generated Donor − Acceptor Cyclopropanes in Domino Reactions. One-Step Enantioselective Synthesis of Pyrrolo[1,2 ‑ a ]quinolines
(American Chemical Society, 2016-03-18)
An easy and straightforward procedure has been developed for the synthesis of highly enantioenriched pyrrolo-[1,2-a]quinolines through a one-pot process that comprises a domino cyclopropane ring opening/aza-Michael/aldol ...
Chiral Bronsted Acid-Catalyzed Enantioselective alpha-Amidoalkylation Reactions: A Joint Experimental and Predictive Study,
(Wiley VCH, 2016-12)
Enamides with a free NH group have been evaluated as nucleophiles in chiral Bronsted acid-catalyzed enantioselective alpha-amidoalkylation reactions of bicyclic hydroxylactams for the generation of quaternary stereocenters. ...
Generation of Tertiary and Quaternary Stereocenters via Palladium-Catalyzed Intramolecular Heck-type Reactions for the Stereocontrolled Synthesis of Pyrrolo[1,2-b]isoquinolines
(Wiley, 2016-04-05)
The generation of quaternary and tertiary stereocenters on C-10 of the pyrroloisoquinoline skeleton through intramolecular Mizoroki-Heck reactions of 2-alkenyl substituted pyrroles and pyrrolidines has been studied. The ...
Perturbation Theory Model of Reactivity and Enantioselectivity of Palladium-catalyzed Heck-Heck cascade reactions
(Royal Society of Chemistry, 2016-04-13)
Enantioselective intramolecular Heck-Heck cascade reactions have emerged as an excellent tool for the construction of polycyclic frameworks, such as Lycorane alkaloids, Xestoquinone and analogues. However, it is particularly ...
