Beilstein Journal of Organic Chemistry, 2011 An efficient synthesis of 1,3-diaryl-4-halo-1H-pyrazoles was achieved. The synthesis involves the [3 + 2] dipolar cycloaddition of 3-arylsydnones and 2-aryl-1,1-dihalo-1-alkenes. The process proceeds smoothly in moderate to excellent yields. 1,3-Diaryl-4-

“One-pot” dispersion ATRP and alkyne-azide Huisgen’s 1,3-dipolar cycloaddition in supercritical carbon dioxide: towards the formation of functional microspheres [PDF]
, 2010 Functional polymers were successfully prepared in scCO2 by combining alkyne-azide 1,3-dipolar Huisgen’s cycloaddition and dispersion ATRP in a “one pot” process using new perfluorinated polymeric amino-based ligands that had a dual role, i.e.

ChemistryEurope, EarlyView.Cathepsin B‐sensitive peptide–adjuvant conjugates are designed, synthesized, and evaluated to deliver an antigenic peptid and an adjuvant targeting Toll‐like receptors 7 and 8 (TLR7/8) to antigen presenting cells. The adjuvant is released by cathepsin B resulting in antigen presentation and TLR mediated T cell activation.

Synthesis of an Enzyme‐Triggered Chitosan‐Based Drug Delivery System for Peri‐Implantitis Prevention
Chemistry – A European Journal, EarlyView.ABSTRACT Dental implants have become a leading solution for tooth loss, yet bacterial infections remain a major complication. Antibacterial implant coatings are an important approach to reduce or prevent bacterial infections at the implant. Given the oral cavity's complex microbiome and the importance of some commensal bacteria, it is crucial to ...
