Nature’s Resource

It was the need to tap increasingly larger volumes of nature s resources and get them to treatment facilities and, ultimately, to consumers that motivated William Smith to lead the way in documenting the need for a potential chronometry. As the practical geologic work carried out by William Smith, Albert Oppel, Charles Lapworth, Robert Kleinpell, and others concerned with recovery of natural resources has revealed that the procedures in chronometry using fossils are basically simple. Many fossiliferous rock... 

The need for sedimentary-rock chronometry and its application remains as valuable a tool in finding and recovering nature s resources today as it was in William Smith s day. Deep ocean-floor explorations have added an interesting, exciting, and still-expanding dimension to sedimentary-rock chronometry.

The work with Porter on cyclic azo compounds coupled Bartlett s free radical studies into his ambitious effort to delineate the border between concerted and biradical cycloaddition mechanisms. Few demonstrations in chemistry have matched the clarity of his 1963 stereochemical proof with Montgomery that the 2 -f 2 cycloaddition of dichlorodifiuoro-ethylene to 2,4-hexadiene involves a biradical intermediate. Through the following decade Bartlett led the biradical parade. His long series of investigations on cycloaddition became particularly important in demonstrating nature s resourcefulness in coping with the supposedly inviolable constraints of orbital symmetry.

These are two chemically different groups of products which have distinct application fields. Both product groups are obtained by reacting maleic acid anhydride (MA) with hydroxyl group(s)-carrying molecules, followed by sulfation of the intermediate product, an ester. Whereas the diester types are mainly made from a few different branched and unbranched alcohols, the monoester are derived from a wide variety of raw materials fatty alcohols, fatty acid alkanolamides, ethoxylated fatty alcohols, fatty acid alkanolamides, their etho-xylates, and others. All these raw materials—with the exception of the branched chains—may be obtained from natural renewable resources. 

The Azeri-Chirag-Guneshli reservoirs contain crude oil with a large volume of associated natural gas. The development of these reserves, have significant implications for the management of Azerbaijan s natural gas resources. 

Various attempts to synthesize biopterin independent of naturally occurring sugars have been carried out (Scheme 11). L-Tartalic acid and (S)-lactic acid were converted to 5-deoxy-L-arabinose (62) and its derivative (67), respectively [76-78]. However, these procedures required multiple steps and cannot be replaced by the procedure using L-rahmnose (65). The stereoselective process of biopterin 7-carboxylic acid (68) starting from E-2-butenoic acid, which is a bulk industrial chemical, looked attractive because the process is thoroughly independent of natural chiral resources, however, it is not applicable to the synthesis of biopterin (30) [79]. 

Synthesized libraries of compounds such as Optiverse are not the only source of new leads. Natural products also play an important role in lead discovery. There are numerous examples where natural products have led to the discovery of new drugs. It is also clear that they represent an inexpensive source of nature s molecular diversity in a lead discovery program. However, a key limitation that must be overcome if leads are to be developed into drugs is they are usually difficult to synthesize, thereby making it more resource-intensive to generate related compounds with better properties.
