Poly(butylene adipate-co-terephthalate) (PBAT) waste gradually accumulates in the environment, posing ecological risks. Enzymatic hydrolysis holds great potential in the end-of-life management of PBAT, but reported enzymes require high reaction temperatures,...

The cooperative Lewis and Brønsted acid catalysis makes convergent synthesis of 3(2H)-furanones through a three-component coupling of 1,3-diynes, alkyl glyoxylates and water. Control experiments support that Lewis acid-catalyzed highly chemo-,...

FB1 is a marine fungus identified as a candidate for plastic degradation in our previous study. This fungus has been recently shown to produce secondary metabolites with significant antimicrobial activity...

Alkyne-carbonyl metathesis is a type of carbon-carbon forming reaction involving the construction a carbon-carbon double bond and a carbonyl group in one transformation. Herein, a Au(I)-catalyzed ring-closing alkyne-carbonyl metathesis protocol...

An atom-economical protocol to construct densely substituted 4-acyl-2-quinolones from -(2-alkynylphenyl)-α-ketoamides has been developed through Sc(OTf)-catalyzed ring-closing alkyne-carbonyl metathesis. Mechanistic experimental studies support that coordinative interaction between Sc(OTf)) and the substrate,...

Gold-catalyzed cycloisomerization of propargyl pyruvates has been developed as a key reaction to prepare maleic anhydride-type natural products. By combining with chemoselective epoxidation of the formed γ-alkylidenebutenolides and oxidative cleavage...

A DBU-mediated, unprecedented formal ring expansion reaction of 2-acyl-3-arylcyclopropane-1,1-dicarbonitriles for the synthesis of multisubstituted furan derivatives is reported. This transformation represents the regioselective ring-opening reaction of cyclopropane-1,1-dicarbonitriles and annulation using...

1,5,6,7-Tetrahydro-4H-indazol-4-one derivatives were successfully synthesized using a one-pot three-component system that combines substituted β-nitrostyrenes, 1,3-cyclohexanediones and phenylhydrazines. This reaction involves a highly efficient domino sequence consisting of the aza-Michael reaction,...

DBU-mediated [4 + 1] annulations of donor-acceptor cyclopropanes with carbon disulfide or thiourea to form 2-aminothiophene-3-carboxylate derivatives have been discovered. This reaction proceeds via the ring opening of donor-acceptor cyclopropanes...
