Search mechanisms

Such techniques mean that the chemical literature may be used more effectively, and that its use can be partially automated. Might this lead to a way of automating organic synthesis To make most molecules there are many strategies which may be successful. If each reaction of each strategy can be evaluated for similarity to a reaction recorded in the literature, it should be possible to develop a route to most molecules by mechanically searching the chemical literature, so that suitable precedent is found for every transformation.

The happy solution to such unhappy situations is already available in certain fields, such as steroids, through mechanized searching. The expansion of the fields in which rapid and efficient searches can be accomplished by machine is ever more essential 2,9,10).

I erminology and nomenclature serve science and technology in a variety of ways, of which the most obvious are the communication and recording of information. Equally important is the use of scientific and technical terms as building blocks for constructing indexes, classification systems, and codes for mechanical searching. 

MNDO calculations have been performed on various conformations of compounds of type (29), and these values have been compared with experimental data derived from variable-temperature NMR <94JPR177>. Selected conformations of caprylolactam (10), as found by a molecular mechanics search, were examined using MNDO-AMl <90MI 927-01 >.
