Heterocyclic compounds occupy a unique place in the realm of organic and medicinal chemistry. A good number of human and veterinary medicines, agrochemicals, insecticides and pesticides, dyes and paints, and so on bear heterocyclic moiety in their molecules. A huge number of natural products having one or more heterocyclic rings are well known to serve the mankind in different ways. The research on synthesis and chemistry of heterocyclic compounds, therefore, has always been on the forefront of organic chemistry, natural product chemistry, and medicinal chemistry. 

The natural world is one of eomplex mixtures petroleum may eontain 10 -10 eomponents, while it has been estimated that there are at least 150 000 different proteins in the human body. The separation methods necessary to cope with complexity of this kind are based on chromatography and electrophoresis, and it could be said that separation has been the science of the 20th century (1, 2). Indeed, separation science spans the century almost exactly. In the early 1900s, organic and natural product chemistry was dominated by synthesis and by structure determination by degradation, chemical reactions and elemental analysis distillation, liquid extraction, and especially crystallization were the separation methods available to organic chemists.

The importance and practicality of asymmetric synthesis as a tool to obtain enantiomerically pure or enriched compounds has been fully acknowledged to date by chemists in synthetic organic chemistry, medicinal chemistry, agricultural chemistry, natural products chemistry, pharmaceutical industries, and agricultural industries. This prominence is due to the explosive development of newer and more efficient methods during the last decade. 

Osmium-catalysed dihydroxylation of olefins is a powerful route towards enantioselective introduction of chiral centers into organic substrates [82]. Its importance is remarkable because of its common use in organic and natural product synthesis, due to its ability to introduce two vicinal functional groups into hydrocarbons with no functional groups [83]. Prof. Sharpless received the 2001 Nobel Prize in chemistry for his development of asymmetric catalytic oxidation reactions of alkenes, including his outstanding achievements in the osmium asymmetric dihydroxylation of olefins. 

The synthesis and application of selenium intermediates and seleno sugars, and the subsequent study of their transformation into various classes of useful precursors and target derivatives, are witnessing rapid new development. This new field of synthetic carbohydrate chemistry offers new methodologies for general organic and natural-product syntheses, and new...
