Ring‐Opening of Epoxides in Water

European Journal of Organic Chemistry, 2011
AbstractEpoxides and water mix well together. The use of water represents an intriguing alternative to organic solvents, not only for developing green processes but also for exploring a totally new and peculiar reactivity. Epoxides react very efficiently in water with several nucleophiles, and several examples in the literature report that the use of ...

Ring-opening Polymerization of Lactones

2018
The synthesis of aliphatic polyesters by the ring-opening polymerization of cyclic monoesters was discovered by Carothers in the 1930s. Since then, a plethora of catalysts and initiators have been discovered to promote this polymerization. Nowadays, steadily increasing attention is paid to organocatalysts and, among them, acids, bases, and H-bond ...

Organocatalytic asymmetric ring-opening of aziridines

Organic & Biomolecular Chemistry, 2008
The organocatalytic ring-opening of N-tosyl protected aziridines by beta-ketoesters under chiral PTC-conditions, leading to the formation of optically active aminoethyl functionalised compounds with up to 99% ee, has been developed.
