Completely recyclable biopolymers with linear and cyclic topologies via ring-opening polymerization of γ-butyrolactone.
Ring-opening polymerization (ROP) is a powerful synthetic methodology for the chemical synthesis of technologically important biodegradable aliphatic polyesters from cyclic esters or lactones. However, the bioderived five-membered γ-butyrolactone (γ-BL) is commonly referred as 'non-polymerizable' because of its low strain energy. The chemical synthesis of poly(γ-butyrolactone) (PγBL) through th...
متن کاملNew α-Methylene-γ-Butyrolactone Derivatives as Potential Fungicidal Agents: Design, Synthesis and Antifungal Activities.
In consideration of the fact that the α-methylene-γ-butyrolactone moiety is a major bio-functional group in the structure of carabrone and possesses some agricultural biological activity, forty-six new ester and six new ether derivatives containing α-methylene-γ-butyrolactone moieties were synthesized, and their fungicidal activities against Colletotrichum lagenarium and Botrytis cinerea were i...
متن کاملSynthesis and QSAR study of novel α-methylene-γ-butyrolactone derivatives as antifungal agents.
Thirty-six new α-benzylidene-γ-lactone compounds based α-methylene-γ-butyrolactone substructure were prepared and characterized by spectroscopic analysis. All compounds were evaluated for antifungal activities in vitro against six plant pathogenic fungi and the half maximal inhibitory concentration (IC50) against Botrytis cinerea and Colletotrichum lagenarium were investigated. Compounds 5c-3 a...
متن کاملSynthesis of trifluoromethyl γ-aminophosphonates by nucleophilic aziridine ring opening.
Phosphonated derivatives of trifluoromethyl aziridine were obtained with good yield from aziridine-2-carbaldehyde by two distinct methods, which resulted in different diastereoselectivities. Using thiols as nucleophiles ring opening reactions of trifluoromethylated derivatives of aziridine-2-phosphonates proceeded regio- and diastereoselectively, giving rise to γ-amino-γ-trifluoromethyl phospho...
متن کاملSynthesis and Characterization of a Novel Carbazole- containing Branched Random Copolymer Derived from α-Norbornene Methylene Polystyrene Macromonomer via Ring-opening Metathesis Polymerization
A novel method for preparing α-norbornene methylene polystyrene macromonomer (NBMPSt) is reported. NBMPSt macromonomer ( Mn = 1.60 × 10 and PDI = 1.26) had glass transition temperature (Tg) of 107 C for polystyrene segment. Since the homopolymerization of NBMPSt macromonomer with number average molecular weight ( Mn ) 1.60 ×10 could not be carried out by ring-opening metathesis polymerization (...
