A Constraints Generator in Structural Determination by Microcomputer
TLDR
A new expert system: a constraints generator for structure determination of natural products for which most structures generators are not very effective and a new algorithm that can avoid the combinatorial explosion during subspectrum/substructure analysis is presented. Expand
Sterolic and triterpenoidic constituents of stem bark of Drypetes gossweileri.
Four compounds have been identified from the stem bark of Drypetes gossweileri by means of 1H- and 13C-NMR spectroscopy, stearic acid, methyl putranjate, and two new compounds: stigmasterol stearateExpand
Ditregra - an auxiliary program for structural determination of diterpenes
This work describes the creation of heuristics rules based on 13 C-NMR spectroscopy that characterize several skeletal types of diterpenes. Using a collection of 2745 spectra we built a databaseExpand
Natural Product Substitution Pattern and Skeletal Recognition Method
TLDR
A methodology for identification of skeletal types of diterpenes based on data base with 1500 compounds isolated from Asteraceae is described, and an example of identification of a new substance is given. Expand
Application of artificial intelligence in organic chemistry. Part XIX. Pattern recognition and structural determination of flavonoids using
This essay describes another improvement to the expert system named SISTEMAT. The purpose of such im- provement is to help chemists who work with natural products to figure out chemical structures.Expand
SISTAX: an intelligent tool for recovering information on natural products chemistry
TLDR
This work describes the development of a new program, named SISTAX, for the expert system SISTEMAT, which allows anyone interested in chemotaxonomy to carry out an intelligent search for organic compounds in databases through chemical structures. Expand
Influence of substituents on aromaticity and stability of hydrocarbons
