Polymerization of Acetaldehyde by Triethylaluminum-Ethanolamine Catalyst

Acetaldehyde substoichiometrically inhibits bovine neurotubulin polymerization.

Acetaldehyde is known to form covalent adducts with tubulin and to inhibit microtubule formation. Available evidence indicates that lysine residues are prominently involved in adduct formation. Previous work has shown that lysines on tubulin can be divided into two general classes based upon their reactivity toward acetaldehyde; those of normal reactivity ("bulk" lysines) and a highly reactive ...

N-acylation of ethanolamine using lipase: a chemoselective catalyst

The N-acylation of ethanolamine (2) with various fatty acids 1a-d and esters of fatty acids 1e-h using Candida antarctica B lipase (Novozym((R)) 435) are described and optimum conditions for selective N-acylation rather than O-acylation are also discussed. Microwave assisted solution phase, solid supported and conventional methods were investigated and results were compared. There is a synergy ...

Polymerization catalyst laser-interference patterning.

The binding of molecular polymerization catalysts to solid supports, in the form of microporous particles or also flat substrates, has been extensively studied. 11 .] The primary aim is to gain control of the morphology of the polymer formed directly during polymerization. This approach can be convenient, for example, in saving additional processing steps if the polymer is formed directly in th...

Ring-expansion metathesis polymerization: catalyst-dependent polymerization profiles.

Ring-expansion metathesis polymerization (REMP) mediated by recently developed cyclic Ru catalysts has been studied in detail with a focus on the polymer products obtained under varied reaction conditions and catalyst architectures. Depending upon the nature of the catalyst structure, two distinct molecular weight evolutions were observed. Polymerization conducted with catalysts bearing six-car...
