Enantioselective Construction of Tetrasubstituted Stereogenic Carbons through Brønsted Base Catalyzed Michael Reactions: α´-Hydroxy Enones as Key Enoate Equivalent
(ACS, 2014-11-25)
Catalytic and asymmetric Michael reactions constitute very powerful tools for the construction of new C–C bonds in synthesis, but most of the reports claiming high selectivity are limited to some specific combinations of ...
Asymmetric Synthesis of Adjacent Tri- and Tetrasubstituted Carbon Stereocenters: Organocatalytic Aldol Reaction of an Hydantoin Surrogate with Azaarene 2-Carbaldehydes
(Wiley-VCH, 2019-07-18)
A bifunctional amine/squaramide catalyst promoted direct aldol addition of an hydantoin surrogate to pyridine 2-carbaldehyde N-oxides to afford adducts bearing two vicinal tertiary/quaternary carbons in high diastereo- and ...
Enantioselective Addition of Alkynyl Ketones to Nitroolefins Assisted by Bronsted Base/H-Bonding Catalysis
(Wiley, 2019-03-21)
Various sets of enolizable alkynyl ketones (including methyl ynones with α-aryl, α-alkenyl, and α-alkoxy groups) were able to react smoothly with nitroolefins with the assistance of bifunctional Brønsted base/H-bond catalysts ...
α-Hydroxy Ketones as Masked Ester Donors in Brønsted Base-Catalyzed Conjugate Additions to Nitroalkenes
(ChemPubSoc Europe, 2018-02-15)
Analysis and Design of a Multilayer DC Bus With Low Stray Impedance and Homogenous Current Distribution
(VDE, 2018-06-05)
The aim of this work is to design a DC bus for a silicon carbide power converter whose application is the automotive sector. This power converter works at high voltage and current levels with high frequencies signals, so ...
Status and advances in Electric Vehicle’s power modules packaging technologies
(VDE, 2016-05-10)
The technology used in the design of the high power density Electric Vehicle (EV) power inverters packaging (power modules electrical, thermal and thermo-mechanical properties) directly
affect the power inverter performance, ...
Wearable Slot Antenna at 2.45 GHz for Off-Body Radiation: Analysis of Efficiency,Frequency Shift, and Body Absorption
(Wiley, 2017-09-12)
The interaction of body-worn antennas with the human body causes a significant decrease in antenna efficiency and a shift in resonant frequency. A resonant slot in a small conductive box placed on the body has been shown ...
RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band
(Wiley, 2019-11-19)
Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were ...
