Описание:
Organocatalysis are an important tool for greener catalytic processes due to the lack of precious metals used. This book explores different organocatalysts and their use in synthesis. Topics covered include zwitterionic imidazolium salt catalysts, asymmetric catalysts in aqueous media, beaker yeast catalysis, organocatalysts for Aldol and Michael reactions, amino acid-based organocatalysts, and Bronsted acidic surfactant organocatalysts.

Описание: This book provides an excellent overview on state-of-the-art of modern organocatalysis. It will be of interest to those who want a general overview of the topic, but also to those who want to learn more about the state-of-the-art, current trends and perspectives in this highly dynamic field of research.

Описание: For over 150 years Britain`s railways have relied on a system of semaphore signalling, but by 2020, all semaphore signals and lineside signal boxes will be gone. This book provides a pictorial record of the last operational signalling and infrastructure on Britain`s railway network, as it applied to the former London, Midland and Scottish Railway.
Описание: This book proposes a novel concept for molecular recognition. In the field of asymmetric synthesis approaching the mature science, asymmetric discrimination and catalytic synthesis of chiral supramolecules still stand as unsolved problems. The extreme difficulty in asymmetric synthesis of such supramolecules may result from the mobile nature of supramolecular chirality. Here the author shows the first highly enantioselective synthesis of mechanically chiral supramolecules. In the presence of a chiral organocatalyst, a mechanically planar chiral rotaxane was obtained with p erfect enantiopurity (>99% ee) with an excellent selectivity. The dynamic and flexible recognition mode enabled asymmetric synthesis of supramolecules with conformational flexibility and mobility. The recognition mode of the catalyst is a contrast to the traditional static and rigid recognition mode of the typical conventional catalysts. The concept of dynamic molecular recognition will be adopted as a novel concept in a wide range of fields beyond the field of organic chemistry, including material chemistry, biochemistry, and medicinal chemistry.

Organocatalysis is considered today one of the three pillars in asymmetric catalysis, along with biocatalysis and organometallic catalysis. The possibility to combine organocatalysis with radical chemistry, photocatalysis and enabling technologies opened new avenues in organic synthesis.
