alpha,omega-Di(vinylene carbonate) telechelic polyolefins: Synthesis by metathesis reactions and studies as potential precursors toward hydroxy-oxazolidone-based polyolefin NIPUs

Current polyurethane (PU) industrial and academic research aims at developing non-isocyanate PUs, referred to as NIPUs. Within this context, we report herein the synthesis of original vinylene carbonate (VC) compounds, subsequently used as chain-transfer agents (CTAs) towards the preparation of alpha,omega-di(VC) telechelic (co)polyolefins from the tandem ring-opening metathesis polymerization (ROMP)/cross-metathesis (CM) of cyclic olefins. Thus, (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl acrylate (VC1), bis((5-methyl-2-oxo-1,3-dioxol-4-yl)methyl) fumarate (VC2), and bis((5-methyl-2-oxo-1,3-dioxol-4-yl)methyl) (E)-hex-3-enedioate (VC3) were synthesized from 4-(hydroxymethyl)-5-methyl-1,3-dioxol-2-one (DMDO-OH). Among these, only VC3 successfully and selectively afforded well-defined. alpha,omega-di(vinylene carbonate) telechelic polyolefins, namely di(VC3)-PCOE and di(VC3)-P(NB-co-CDT), from the ROMP/CM of COE, and norbonene (NB)/trans,trans,cis-1,5,9-cyclododecatriene (CDT), respectively, using Grubbs? 2nd-generation ruthenium catalyst (G2) under mild operating conditions (CH2Cl2, 40 C, 3 h). Preliminary investigations on the reactivity of a model VC, namely 4,5-dimethyl-1,3-dioxol-2-one (DMDO), towards nucleophiles such as a primary or secondary amines, promisingly showed the formation of hydroxy-oxazolidone compounds 1 and 2, and oxo-urethane 3 species, respectively. Yet, the ultimate reaction of di(VC3)-PCOE with 2,2?-(ethylenedioxy)bis(ethylamine) (EDR-148) did not give the expected poly(di(hydroxy-oxazolidone)polyolefin)s polyaddition type of NIPUs; competing amidation and/or dehydration or urea formation reactions evidenced by detailed NMR, FTIR and MS analyses, were proposed to account for this inefficiency.

Total synthesis and absolute stereochemical assignment of (+)- and (-)-galbulimima alkaloid 13

We describe the total synthesis of (+)- and (-)-galbulimima alkaloid 13. The absolute stereochemistry of natural (-)-galbulimima alkaloid 13 is revised to 2S. Sequential use of catalytic cross-coupling and cross-metathesis reactions followed by an intramolecular Diels-Alder reaction provided the required trans-decalin AB-ring system and masked the C16 carbonyl as an N-vinyl carbamate for late-stage unveiling in the form of the necessary C16 enone. A vinyl radical cyclization secured the C-ring, while successful execution of our strategy for introduction of the CDE-ring system in complex galbulimima alkaloids provided the target pentacycle with complete diastereoselection.

A novel palladium-catalyzed intermolecular aminocarbonylation of alkenes has been developed in which the employment of hypervalent iodine reagent can accelerate the intermolecular aminopalladation, which thus provides the successful catalytic transformation. The current transformation presents one of the most convenient methods to generate beta-amino acid derivatives from simple alkenes.

Catalytic Radical Process for Enantioselective Amination of C(sp3)?H Bonds

A new catalytic radical system involving CoII-based metalloradical catalysis is effective in activating sulfamoyl azides for enantioselective radical 1,6-amination of C(sp3)?H bonds, affording six-membered chiral heterocyclic sulfamides in high yields with excellent enantioselectivities. The CoII-catalyzed C?H amination features an unusual degree of functional-group tolerance and chemoselectivity. The unique reactivity and stereoselectivity is attributed to the underlying stepwise radical pathway. The resulting optically active cyclic sulfamides can be readily converted into synthetically useful chiral 1,3-diamine derivatives without loss in enantiopurity.

Electrochemical degradation of nitrofurans furazolidone by cathode: Characterization, pathway and antibacterial activity analysis

Antibiotics existing in wastewaters must be degraded to eliminate its antibacterial activity before discharging into the environment. Electrochemical reduction by continuous electrons supply can degrade various refractory pollutants, however, the information about the feasibility and characterization of the cathodic degradation of nitrofurans antibiotic furazolidone (FZD) is scarce. Here, we investigated the degradation of FZD using a poised cathode electrochemical reactor. The cyclic voltammetry (CV) preliminarily proved the feasibility of FZD degradation on cathode. In contrast to the different buffer solutions concentrations, buffer types, and initial FZD concentrations which only had obvious impact on the FZD degradation efficiency, different cathode potentials had significant effects both on the FZD degradation efficiency and degradation products composition. Catholyte PBS could be replaced by Na2CO3-NaHCO3 and NaCl buffer solution for the FZD degradation. The cathodic degradation pathway of FZD was proposed based on intermediate products analysis. When the cathode potential was lower than -0.75V, both the furan ring and oxazole ring of FZD were destroyed to generate linear chain products after N-N bond disconnection, suggesting that the high toxic biological metabolite of FZD, 3-amino-2-oxazolidinone (AOZ) could be detoxified by cathodic degradation. This study suggests that the electrochemical reduction could serve as a potential strategy for the treatment of FZD and AOZ containing wastewater.
