Asymmetric Synthesis - Essay Example

Comments (0) Cite this document
With man's present need to acquire significant instruments for the effective asymmetric synthesis of compound organic molecules, the study of catalytic asymmetric synthesis has become an important aspect of organic chemistry. Generally, popular catalysts which are usually used by organic chemists utilize transition metals in order to trigger a chemical reaction in the presence of a chiral ligand (Noyori, 1994.)

This includes its role in the production of food flavorings and medicines for different ailments like malaria.
Additionally, the popularity of cinchona alkaloids over the years is also because of its qualifications in the three primary criteria of catalysts, which are as follows: 1) the diversity of reactions that the catalyst can trigger; 2) the accessibility of both enantiomeric antipodes of the catalyst at an affordable cost; and 3) the stability of the catalyst.
The research aims to study the catalytic asymmetric synthesis of the popular two pairs of cinchona alkaloids which are enantiomeric in nature: cinchonine and cinchonidine, and; quinine and quinidine. The researcher aims to study the two pairs by isolating them through extraction of the bark of the cinchona tree; a native of tropical regions. Due to their widespread use, all four members are readily available in large quantities from most chemical suppliers.
Furthermore, before conducting several experiments for the research, the researcher will gather enough materials documenting the history of cinchona alkaloids. ...
erature section of the research, which will include information about cinchona alkaloids from one of the earliest uses of cinchona alkaloids in asymmetric catalysis which was demonstrated by Pracejus in the 1960's to catalyze the asymmetric alcoholysis of ketenes (Pracejus, 1964) to its modern uses.
Moreover, the study's related literature will consist of theories proposed about the asymmetric synthesis of cinchona alkaloids by chemists of different ages. One interesting theory which will contribute to the study of the alkaloid's catalytic asymmetric synthesis is that the alcohol is activated via a hydrogen bond with the tertiary amine of benzoylquinine. Addition of the alcohol to the ketene is followed by quenching of the resultant enolate by the chiral ammonium salt. The resultant esters are isolated in up to 76% enantiomeric excess. The research will strive to replicate the experiments conducted to support this theory.
Also, with the proliferation of recent publications studying cinchona-ketene systems for asymmetric synthesis (Blake, 2001), the study will investigate different assumptions about the asymmetry in the synthesis of cinchona alkaloids. One of the most noticeable of these recent publications which the researcher intends to focus is Lectka's -halogenation of acid chlorides (Wack, 2001). Lectka stated that the benzoylquinine-ketene system reacts with quinone based electrophilic halogenating reagents to yield activated -halogenated esters with enantioselectivities as high as 99%, and with good yields. The study will try to prove this through catalytic asymmetric fluorination, where cinchona derivatives have already been used, though only stoichiometrically (Muiz, 2001).
However, despite the efforts to base certain experiments upon previous studies, the ...Download file to see next pagesRead More

Asymmetric information and market disequilibrium
But in reality the pool of information knowledge varies with certain degrees among the agents of the markets i.e., among the buyers and the sellers leading to market distortions or attainment of disequilibria (Economics of organization, slide 3, 5) This has been a broad domain of study for the economists where market distortions occur as a result of asymmetry in information among the buyers and the sellers although they are willing eagerly for performing transactions in the market.

Asymmetric or Symmetric Encryption
The methods available to encrypt data involves asymmetric and symmetric means. The present article emphasizes upon the benefits of these methods for data protection. Introduction Encryption of data is necessary in transmitting information through electronic means, to safeguard- data or information, sensitive documents and private communications made through internet, else the information could be distorted, filched, or misrepresented.

Asymmetric Key/Symmetric Key
Hashing algorithms are utilized to ensure data is not modified during transit – that is, to ensure data integrity. Lastly, signature based algorithms are used for authentication by providing a digital or electronic signature of the user. As an ABC institute of research has to protect highly sensitive information from its rivals, we will discuss symmetric and asymmetric encryption algorithms in this scenario.

Reactivity of M-C bonds and catalytic formation of heterocycles
Heterocyclics are thus the exact opposite of homocyclic compounds whose rings only contain atoms of a one element. Despite the fact that heterocyclic compounds are likely to be inorganic, most of them have one carbon in their structures. The importance of heterocyclics in the synthesis of chemical compounds led to the emergence and spread of heterocyclic chemistry as branch of the discipline(Boutadla et al., 2009).
