Acid-base pair-mediated copolymerization of acid-sensitive epoxides and cyclic anhydride for synthesizing recyclable thermoplastics [PDF]

Nature Communications
Developing low-cost, high-performance, and chemically recyclable alternatives to bulk polyolefin commodities is critical. Aromatic polyesters synthesized via ring-opening copolymerization (ROCOP) of phthalic anhydride (PA) and olefin-derived epoxides are

Multi-functional epoxides cross-linked collagen sponges for tissue engineering scaffolds

Collagen and Leather, 2023
With the efficient cross-linking abilities and the flexible regulation abilities to the performances of cross-linked products, the multi-functional aliphatic epoxides were once widely used to cross-link the collagen-based materials in the last century ...

Reactions of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I induced by Bf3·Et2O/Bu4NBr [PDF]

Journal of the Serbian Chemical Society, 2006
The reaction of α-4(20)-epoxy-5-O-mesyltriacetyltaxicine I (2) with BF3·Et2O/Bu4NBr can give rise to 4 different products. Each of these products can be obtained selectively, under the appropriate reaction conditions.

Allylic alcohols and amines by carbenoid eliminative cross-coupling using epoxides or aziridines

Beilstein Journal of Organic Chemistry, 2021
α-Lithiated terminal epoxides and N-(tert-butylsulfonyl)aziridines undergo eliminative cross-coupling with α-lithio ethers, to give convergent access to allylic alcohols and allylic amines, respectively.

Formal [3+2] Cycloaddition Reactions of Electron-Rich Aryl Epoxides with Alkenes under Lewis Acid Catalysis Affording Tetrasubstituted Tetrahydrofurans

Molecules, 2020
We report on the regio- and stereoselective synthesis of tetrahydrofurans by reaction between epoxides and alkenes in the presence of a Lewis acid. This is an unprecedented formal [3+2] cycloaddition reaction between an epoxide and an alkene.

Formation and metabolism in vitro of 5,6-epoxides of cholesterol and β-sitosterol

Journal of Lipid Research, 1974
The formation of 5α,6α- and 5β,6β-epoxides of cholesterol and β-sitosterol in rat liver subcellular fractions has been studied. The results show that the epoxidation seems to occur only in connection with the nonspecific tissue oxidation of the sterols ...
