Visible Light‐Mediated Preparation of a Key Intermediate Employed in the Synthesis of Zolpidem and Several Analogs

Chemistry – An Asian Journal, EarlyView.
A new visible light‐induced method is reported for the C3‐alkylation of imidazo[1,2‐a]pyrimidines and ‐pyridines with aryldiazoacetates. This protocol can be performed in open air and serves as a convenient entry to several known and new molecules. A formal synthesis of zolpidem is achieved by changing the alkylating agent to an appropriate hypervalent

Iron Catalysts with Silyl‐NHC Chelate Ligands: Controlling Factors for Hydroboration vs. Dehydrogenative Borylation of Olefins

Chemistry – An Asian Journal, EarlyView.
Silyl‐NHC chelate iron complexes with various substituents on NHC were synthesized and demonstrated to be active catalysts for hydroboration and dehydrogenative borylation of olefins. The selectivity of these borylation reactions is significantly controlled by the steric bulk of a substituent on the NHC nitrogen.

Saccharinate‐Based Ionic Liquids and Lithium Battery Electrolytes

Batteries &Supercaps, EarlyView.
Fluorine‐free ionic liquids (ILs) with saccharinate anion coupled to ether‐functionalized pyrrolidinium/imidazolinium cations exhibit promising thermal, transport, and electrochemical properties. The imidazolinium‐based ILs offer higher electrochemical stability, while the pyrrolidinium‐based ILs display superior ion transport.

Bioactivity profiles of progressively ring‐fluorinated cyclohexyl motifs in the WKYMVm peptide as formylpeptide FPR2 agonists and in keto‐piperazines as anti‐trypanosome agents.

ChemBioChem, Accepted Article.
A series of all‐cis ring fluorinated cyclohexylalanines with progressively increasing levels of vicinal fluorines, as well as 4‐fluorophenylalanine and pentafluoroarylphenylalanine were introduced into the WKYMVm peptide in place of its tyrosine residue, for assays against the G‐protein coupled formylpeptide receptor, FPR2.
