Highly enantioselective resolution of terminal epoxides using polymeric catalysts

, 2002
Poly-salen-Co(III) complexes were employed in the hydrolytic kinetic resolution (HKR) of terminal epoxides and ee's up to 98% were obtained. In the HKR of epichlorohydrin, the polymeric catalysts can be recovered and modified for recycling. The recovered

Cyclic Processability of Functional Liquid Crystalline Epoxy Networks via Dynamic Ester Bonding

Journal of Applied Polymer Science, EarlyView.
This work reports the successful reprocessing of liquid crystal epoxy networks through two distinct modes—welding of clean breaks and reconstitution from shredded material—without significant loss of functionality. Thermal and mechanical characterization shows stability in the shape memory behavior and glass transition temperature over multiple ...

Stabilization by Crosslinking of β‐Galactosidase Immobilized by Adsorption for Application in a Continuous Lactose Removal Process

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Adsorption is the simplest method of enzyme immobilization, but it often requires additional treatments to improve stability. These treatments, however, may impact enzymatic activity. This study investigated the effect of crosslinking on the stability of β‐galactosidase immobilized by adsorption on A‐568 resin and its implications for ...

Clinical relevance of pharmacogenomic information for improving prescribing practices in acutely admitted older medical patients

British Journal of Clinical Pharmacology, EarlyView.
Aims Safe prescribing and effective medication review during acute hospitalization depends on accurate information about liver and kidney function because these organs are responsible for the elimination of most medications. While estimates for kidney function are widely used, comparable markers of hepatic drug‐metabolizing capacity are not routinely ...

Tin(IV)-Porphyrin Tetracarbonyl Cobaltate: An Efficient Catalyst for the Carbonylation of Epoxides

, 2019
Cationic tin(IV) porphyrins with tetracarbonyl cobaltates were synthesized, exhibiting bifunctional catalytic reactivity. The Lewis acidic tin-porphyrin center activated epoxides; concurrently, cobalt carbonyl anions efficiently opened epoxides and ...
