Chemistry – A European Journal, EarlyView.Per‐ethylene‐glycol (EG)‐functionalized resorcin[4]arenes containing 12, 16, and 20 EG groups namely compounds 1d, 1e, and 1f, respectively, were prepared and found to self‐assemble, in organic solvents, into hexameric capsules. These capsules are more dynamic than the ones prepared based on alkyl substituted resorcin[4]arenes.

Novel (3+2) dipolar cycloadditions of pyridinium ylides [PDF]
, 2017 This thesis describes advances in novel (3+2) dipolar cycloadditions of pyridinium ylides, their reactions with electrophilic alkenes afford tetrahydroindolizines which can possess alkaloid-like scaffolds.

Chemistry – A European Journal, EarlyView.This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Oxaziridines: Versatile Reagents in Modern Organic Synthesis
The Chemical Record, EarlyView.Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
