Iridium-catalyzed asymmetric transfer hydrogenation of quinolines with Hantzsch esters
, 2007 The iridium-catalyzed enantioselective transfer hydrogenation of quinolines with Hantzsch esters was developed with up to 88%, ee using [Ir(COD)Cl](2)/(S)-SegPhos/I-2 as a catalyst.

Ag─S Sites Steer Furfural Electroreduction to Furfuryl Alcohol
Angewandte Chemie, EarlyView.A simple sulfide incorporation strategy turns silver into a highly active and selective catalyst for furfural electroreduction to furfuryl alcohol. Experiments combined with density functional theory reveal how isolated S sites promote hydrogenation while suppressing hydrofuroin coupling, enabling selective biomass upgrading.

Angewandte Chemie, EarlyView.Catalytic strain‐release ring opening and functionalizations of 1‐azabicyclo[1.1.0]butanes (ABBs) represent a promising strategy for accessing diverse azetidine products. These transformations proceed via polar pathways, radical pathways, and hybrid mechanisms that combine both.

Evolution of PIKK family kinase inhibitors: A new age cancer therapeutics
Frontiers in Bioscience-Landmark, 2020 Phosphatidylinositol-3 kinase-related kinases (PIKKs) belong to a family of atypical serine/threonine kinases in humans. They actively participate in a diverse set of cellular functions such as meiotic, V(D)J recombination, chromosome maintenance, DNA ...

Synthesis of linear azolo and pyrido quinolines from quinoline derivatives
, 2008 Angular N-tricyclic systems as triazolo[ 4,5-f]quinolines, triazolo[ 4,5-h] quinolines, imidazo[ 4,5-f]quinolines, imidazo[ 4,5-h]quinolines were in the past obtained by connection of either f or h sides of the quinoline ring and both the adjacent carbon
