单词 Organocatalysis
释义

Organocatalysis

原声例句
2021诺贝尔得主访谈录

An asymmetric organocatalysis that means that the catalyst, our small well-defined organic catalyst is asymmetric, that it's chiral.

不对称有机催化也就是说,我们的小而明确的有机催化剂是不对称的,是手性的。

2021诺贝尔得主访谈录

The Nobel Prize Committee are recognizing the component of our research which is in the area of organocatalysis.

诺贝尔奖委员会认可了我们在有机催化领域的研究。

经济学人(汇总)

The result of these two pieces of work is a field called asymmetric organocatalysis (the asymmetric part of the name referring to its ability to generate pure enantiomers), that is now rippling through industrial chemistry.

这两项工作的结果是一个被称为不对称有机催化的领域(这个名称的不对称部分指的是它产生纯对映体的能力)现在正席卷工业化学界。

2021诺贝尔得主访谈录

And when we say organocatalyst or organocatalysis, we mean that the catalyst is a small and well-defined organic molecule that consists mainly of elements such as carbon, hydrogen, oxygen, nitrogen, maybe, sulfur, phosphorus, silicon, but no metals.

当我们说有机催化剂或有机催化时,我们的意思是催化剂是一种小而明确的有机分子,主要由碳,氢,氧,氮,也许还有硫,磷,硅等元素组成,但没有金属。

有机催化

有机催化(Organocatalysis)是指只含碳、氢、硫和其他非金属元素的“有机催化剂”对化学反应的催化作用。这是目前有机合成中最热门的领域之一。它又可按照催化机理分为烯胺活化、亚胺离子活化、SOMO活化、氢键活化(硫脲催化、手性质子酸催化、寡肽催化、金鸡纳生物碱催化)、手性相转移催化剂活化和氮杂环卡宾活化等。

有机催化反应实际上很早就有报道。20世纪70年代发现的Hajos-Parrish-Eder-Sauer-Wiechert反应就是脯氨酸催化的分子内羟醛反应。2000年,List等将此反应用于不对称的分子间羟醛反应,在JACS上发表题为《脯氨酸催化的直接不对称羟醛反应》的通讯,标志着有机催化的复兴。同年MacMillan创制出“有机催化”一词,并提出一种全新的有机催化机理——亚胺活化。

Organocatalysis 有机催化


Justus von Liebig's synthesis of oxamide from dicyan and water represents the first organocatalytic reaction, with acetaldehyde further identified as the first discovered pure

In organic chemistry, the term organocatalysis (a portmanteau of the terms "organic" and "catalyst") refers to a form of catalysis, whereby the rate of a chemical reaction is increased by an organic catalyst referred to as an "organocatalyst" consisting of carbon, hydrogen, sulfur and other nonmetal elements found in organic compounds. Because of their similarity in composition and description, they are often mistaken as a misnomer for enzymes due to their comparable effects on reaction rates and forms of catalysis involved.
