Chirality and catalysis with aromatic N-fused heterobicyclic carbenes
(Royal Society of Chemistry, 2016)
The benzoannulation of the most common families of aromatic NHCs, imidazol-2-ylidenes and 1,2,4-triazol-3-ylidenes, results in heterobicyclic imidazo[1,5-a]pyridin-3-ylidenes (ImPy's) and [1,2,4]triazolo[4,3-a]pyridin-3-ylidenes ...

Room Temperature Ionic Liquids in Asymmetric Hetero-Ene Type Reactions: Improving Organocatalyst Performance at Lower Temperatures
(MDPI, 2021-01)
Abstract: Room temperature ionic liquids (RTILs) have been widely used as (co)solvents in several catalytic processes modifying, in most of the cases, the catalyst activity and/or the selectivity for the studied reactions. ...

Solvent-free synthesis of quaternary alpha-hydroxy alpha-trifluoromethyl diazenes: the key step of a nucleophilic formylation strategy
(Royal Society of Chemistry, 2016)
An efficient, scalable and operationally simple one-pot, 2-step strategy for the nucleophilic formylation of trifluoromethyl ketones is presented. The key step is an unprecedented diaza-carbonyl-ene reaction of formaldehyde ...

Studies on the Synthesis of 2-Alkyl-5-aryl-1,3,4-oxadiazolines from N-Acylhydrazones
(2012)
Reaction of N-acylhydrazones with benzyloxyacetyl chloride in the presence of i-Pr 2EtN affords new 1,3,4-oxadiazolines in excellent yields (72-95%), under mild reaction conditions and in short reaction times. The structures ...

Pd-Catalyzed Dynamic Kinetic Asymmetric Cross-Coupling of Heterobiaryl Bromides with N-Tosylhydrazones
(American Chemical Society, 2022)
A dynamic kinetic asymmetric Pd-catalyzed cross-coupling reaction of heterobiaryl bromides with ketone N-tosylhydrazones for the synthesis of heterobiaryl styrenes is described. The combination of Pd(dba)2 as a precatalyst ...
