Designing heterogeneous catalysts that ensure efficient recycling and reuse of the catalyst in a wide range transformations remains real challenge. In this contribution, targeted copolymers are used as supports for development asymmetric catalysts. They made up two methacrylate monomers, 3‐azidopropylmethacrylate (AZMA), 2‐methoxyethyl (MEMA) diluting agent. Polymerization was carried out using Cu(0)‐mediated reversible deactivation radical polymerization (RDRP), yielding with controlled...
Novel photochromic polymers highlight through their solid-state optical properties the key role of grafting onto coloration and fading kinetics.
2-Nitro thioglycosides can be prepared by the Michael addition of thiophenol to 2-nitroglycal derivatives. NIS/TMSOTf activation these 2-nitro thioglycosides, in presence alcohols, rapidly and cleanly led desired glycosides good yield β-selectivity. Reduction nitro group allowed generation corresponding 2-acetamido glycosides.
With respect to the increasing need for fully characterizing surface-tethered polymer brushes, capacity of quantitative IR-Fourier transform infrared (FTIR) spectroscopy using a multiple-internal-reflection Si prism as attenuated total reflection (ATR) element is investigated directly characterize surface chemical modifications occurring during surface-initiated controlled polymerization. A simple two-step strategy used involving first covalent grafting atom transfer radical polymerization...
In the previous work, poly(4-vinyl dimethyl dipicolinate) (PVDPM) polymer grafted on poly(vinyl chloride) (PVC) and poly(ethylene terephthalate) (PET) film or industrial fibers proved its efficiency for trapping uranium many lanthanides in a liquid environment. this we propose to graft our active obtained by electrospinning increase specific surface of final material. To address challenge, grafting electrospun chlorinated (PVC-co-CPVC) using supplemental activation reducing agent atom...
Copolymers are valuable supports for obtaining heterogeneous catalysts that allow their recycling and therefore substantial savings, particularly in the field of asymmetric catalysis. This contribution reports use two comonomers: Azido-3-propylmethacrylate (AZMA) bearing a reactive azide function was associated with 2-methoxyethyl methacrylate (MEMA), used as spacer, ATRP synthesis copolymers, then post-functionalized propargyl chromium salen complex. The controlled homopolymerization MEMA...
The use of glycals as acceptors in glycosylation reactions is hampered by their sensitivity to acids. We report here on the successful mild Lewis acid [Sn(OTf)2] catalyst for with O-glycosyl trichloroacetimidates and development this method construct a key intermediate synthesis mucin type O-glycans. To end, chemoselective nitration O-glycosylated glycals, stereoselective threonine addition, reduction nitro group amino an efficient procedure avoiding expensive was performed.
