Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, EarlyView.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Angewandte Chemie, EarlyView.A metal‐ and oxidant‐free electrochemical multicomponent di‐functionalization strategy that rapidly converts 1,1‐disubstituted alkenes into α‐tertiary primary amines with simultaneous installation of bio‐relevant sulfur or selenium motifs was devised for late‐stage functionalization. ABSTRACT Quaternary carbon centers, especially those bearing nitrogen,

Catalysis Communications, 2012 Abstract An efficient methodology to access benzoate derivatives via tandem benzylic oxidation/oxidative esterification of benzylic alcohols with phenols catalyzed by ruthenium/NHC was developed. This operationally simple one-pot process uses O 2 as the clean oxidant, producing esters in good to excellent yields.

Nitro Reduction‐Based RNA Control and Ultrafast Release
Angewandte Chemie, EarlyView.A chemical RNA caging–uncaging strategy based on nitro reduction is described. Nitroaryl groups introduced via acylation temporarily block the functions of diverse RNAs in vitro and in living cells. Treatment with a diboronic acid–bipyridine mixture rapidly reduces the nitro groups, releasing RNAs and restoring their activity.

Functional and Network PHAs via Stereoselective Polymerization and Tailored Post‐Transformation
Angewandte Chemie, EarlyView.Catalyst‐controlled stereoselective (co)polymerization of functionalized lactones produces vinyl‐, allyl‐, and propargyl‐functionalized PHAs with high syndiotacticity and a broad applicable temperature window, which can be further transformed into crosslinked PHA thermosets, elastic supramolecular networks, and functional grafts. ABSTRACT Incorporation

Tuning the Synthesis of Manganese Oxides Nanoparticles for Efficient Oxidation of Benzyl Alcohol
Nanoscale Research Letters, 2017 The liquid phase oxidation of benzyl alcohol is an important reaction for generating benzaldehyde and benzoic acid that are largely required in the perfumery and pharmaceutical industries. The current production systems suffer from either low conversion or over oxidation.
