A Crystalline Ylide‐Stabilized Stibenium Cation

open access: yesEuropean Journal of Inorganic Chemistry, Volume 29, Issue 17, 17 June 2026.
The isolation of a stibenium cation stabilized by two thiophosphinoyl‐tethered ylide groups is reported. The cation is accessible via salt metathesis of the metalated ylide with SbCl3 and features CSb single bonds, with lone pairs remaining localized at the ylidic carbon atoms.

2.8 Recent Advances in N-Heterocyclic Carbene Organocatalysis

open access: yes, 2018
In recent years, organocatalysis has seen a rapid rise in popularity and this has led to a subsequent increase in the research output of the area, with organocatalysis by N-heterocyclic carbenes (NHCs) playing a significant role.

New approaches to organocatalysis based on C–H and C–X bonding for electrophilic substrate activation

open access: yesBeilstein Journal of Organic Chemistry, 2016
Hydrogen bond donor catalysis represents a rapidly growing subfield of organocatalysis. While traditional hydrogen bond donors containing N–H and O–H moieties have been effectively used for electrophile activation, activation based on other types of non ...

Enantioselective homogeneous catalysts for the synthesis of fluorinated organic compounds

open access: yes, 2012
This thesis is divided into three main results chapters that reflect the path my research took. In the first results chapter, the first organocatalyst for the carbonyl-ene reaction was discovered and found to give high conversion using 1,3-bis(3,5-bis ...

Asymmetric synthesis of tetrahydroquinolines through supramolecular organocatalysis

open access: yes, 2014
Functionalized chiral tetrahydroquinolines were synthesized through supramolecular organocatalysis using quinidine-NH-thiourea 3c/L-phenylalanine 4i followed by reductive amination from the simple ...

Substrate‐Controlled Organocatalytic Divergent Annulations of γ, γ’‐Alkylidene Indane‐1,3‐Diones With Enals

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
A substrate‐dependent, regio‐ and stereocontrolled diversity‐oriented organocatalytic vinylogous Michael addition/cyclization cascade of γ, γ’‐alkylidene indane‐1,3‐diones with enals, using secondary amines as the catalyst, has been developed. A substrate‐dependent, regio‐ and stereo‐controlled diversity‐oriented organocatalytic vinylogous Michael ...

Enantioselective Tandem Povarov/Urech–Read Reaction for the Synthesis of Dihydroquinoline/Hydantoin Hybrids

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 11, 3 June 2026.
Herein, an organocatalytic asymmetric synthesis of dihydroquinoline/hydantoin hybrids is described. The synthetic protocol involves a tandem reaction comprising a phosphoric acid–catalyzed initial Povarov dimerization of in situ generated imine/enamine mixtures under tautomeric equilibrium, followed by a Urech–Read reaction of the 1,2‐dihydroquinoline ...
