Enzymatic Desymmetrization

Symmetric organic compounds are generally obtained inexpensively, and therefore they can be attractive building blocks for the total synthesis of various pharmaceuticals and natural products. The drawback is that discriminating the identical functional groups in the symmetric compounds is difficult. Water is the most environmentally benign and inexpensive solvent. However, successful organic reactions in water are rather limited due to the hydrophobicity of organic compounds in general. Therefore, desymmetrization reactions in aqueous media are expected to offer versatile strategies for the synthesis of a variety of significant organic compounds. This review focuses on the recent progress of desymmetrization reactions of symmetric organic compounds in aqueous media without utilizing enzymes.

Alternative Approaches

: Micellar chemistry is gaining considerable interest among organic chemists because these reactions are carried out in environmentally benign solvents like water. Owing to the exhaustive use of toxic solvents in carrying out the different chemical reactions, there is a pressing need for alternative approaches either environmental friendly or having minimum impact on the environment. In this article, we aim to discuss the various aspects of micellar chemistry viz-a-viz its role in guiding the chemical reactions. Micelles help to drive various kinds of organic reactions including oxidations, reductions, carbon-carbon bond formation, carbon-heteroatom bond formation, multi-component reactions, Pd-coupling reaction, olefin metathesis reaction, Morita-Baylis-Hillman reaction, etc. in water.
