WebJan 3, 2024 · A series of new hyperbranched aliphatic poly(β-thioether ester)s were prepared by the enzymatic ring-opening polycondensation of 1,4-oxathiepan-7-one (OTO) and AB 2 /ABB’ comonomer with acid-labile β-thiopropionate groups. Two kinds of comonomers, methyl 3-((3-hydroxy-2-(hydroxymethyl)propyl)thio)propanoate (HHTP) and … WebMay 7, 2024 · The combination of the thiol-Michael addition reaction and the Diels–Alder reaction (DA) was exploited to synthesize thermoset elastomers from 5-hydroxymethylfurfural derivative. The first step involved the synthesis of linear poly(β-thioether ester) via the thiol-Michael addition polymerization of 2,5-furan diacrylate (2,5 …
WebAll four poly(β-thioether ester ketal) networks exhibited degradation behavior characteristic of a surface erosion process. The networks showed mechanical (low modulus) and thermomechanical properties (low T g) typical of thiol–ene thermosets with minimal influence from the structure of the diketal linkage. To highlight the advantages of ... WebDec 10, 2016 · The acyl phosphate reaction is a means of generating a thioester. The reaction works in reverse as well - the energy of a thioester bond (Δ G °′ = −7.5 kcal/mol for hydrolysis) can be conserved in the terminal phosphoanhydride bond of ATP. Other types of thioesters that occur in biochemical processes are indicated.
In organic chemistry, thioesters are organosulfur compounds with the molecular structure R−C(=O)−S−R’. They are analogous to carboxylate esters (R−C(=O)−O−R’) with the sulfur in the thioester replacing oxygen in the carboxylate ester, as implied by the thio- prefix. They are the product of esterification of a carboxylic acid (R−C(=O)−O−H) with a thiol (R'−S−H). In biochemistry, the best-known thioesters are derivatives of coenzyme A, e.g., acetyl-CoA. The R and R' represent WebJun 11, 2024 · Renewable Poly(Thioether-Ester)s from Fatty Acid Derivatives via Thiol-Ene Photopolymerization
WebMar 8, 2024 · Thioether ester groups as cleavable linkages are interesting because they can be easily synthesized via efficient thiol–ene reactions. We demonstrate here that the hydrolysis rate and selectivity of thioether ester groups can be tuned by several orders of magnitude by insertion of substituent groups.
