Compound collections INDEX

Both common and systematic names of compounds are used throughout this volume, depending on which the Editor-in-Chief felt was more appropriate The Chemical Abstracts indexing name for each title compound, if it differs from the title name, is given as a subtitle Systematic Chemical Abstracts nomenclature, used in both the 9th and 10th Collective Indexes for the title compound and a selection of other compounds mentioned in the procedure, is provided in an appendix at the end of each preparation. Registry numbers, which are useful in computer searching and identification, are also provided in these appendixes. Whenever two names are concurrently in use and one name is the correct Chemical Abstracts name, that name is adopted. For example, both diethyl ether and ethyl ether are normally used. Since ethyl ether is the established Chemical Abstracts name for the 8lh Collective Index, it has been used in this volume The 9th Collective Index name is 1,1 -oxybisethane, which the Editors consider too cumbersome. 

This review includes most of the published articles from the defined area and excludes only imidazoquinolines, which were reviewed in Weissberger-Taylor s series The Chemistry of Heterocyclic Compounds (81MI1). Comprehensive Heterocyclic Chemistry II (96MI1) mentioned only some of the azoloquinolines in the first edition the authors omitted citations about this type of compounds. The trend toward interest in these compounds can be illustrated by the number of citations in Chemical Abstract as shown in Table I. Besides Chemical Abstracts Substance/Subject (Collective) Indexes, the MDL database search has been used. 

There is also a fourth division of Beilstein (systems 4721 -4877) that covers natural products of uncertain structure rubbers, sugars, and so on. These are treated in vols. 30 and 31, which do not go beyond 1935 and which are covered in the collective indexes. These volumes will not be updated. All such compounds are now included in the regular Beilstein volumes. 

Compounds newly reported in the fifth supplement that are in a volume whose index has not yet been published will not be found by this procedure. To find them in Beilstein it is necessary to know something about the system (see Ref. 21), but they may also be found by consulting CA indexes beginning with the sixth collective index, or by using Beilstein online. 

The same template as for compound 71 was used by Peukert et al. for a 2D similarity search in the Aventis in-house compound collection [144]. 75 Compounds with a similarity index >0.80 were biologically tested. The moderately active l-carboxy,8-sulfonamido-naphthalene (IC50 = 9.5pM), with insufficient chemical stability, was the starting point for the design of substi-... 

The indexing of organic compounds described since 1922 has been taken over by the Chemisches Zentralblatt, which follows the system hitherto discussed. The collective indexes of this journal for 1922 to 1924,1925 to 1929, and 1930 to 1934 continue the classifying work of M. M. Richter. In these indexes the references are to the Zentralblatt itself. Each year of the Zentralblatt, from 1925 onwards, contains a formula index covering the annual increment of literature abstracted in this comprehensively planned journal. These formula indexes are amalgamated every few years into a collective index and individually they constitute the reference works for the period which has elapsed since the appearance of the last collective index. Consequently, when it is desired to have complete information from the whole literature about an organic substance, the following works must be consulted at the present day ... 

Individual compounds are indexed under their appropriate group titles, but since most of the available compounds are liquids with similar hazardous properties, these will be described collectively here. These aspects of the class have been extensively reviewed and documented [1,2,3,4,5,6,7,8],... 

There have been many developments in the chemistry of the 1,3,5-triazines since the comprehensive reviews of Smolin and Rapoport (59HC(13)1) and Modest (B-61MI22000, p.627). It is impossible to include all the vast range of 1,3,5-triazines reported in the literature 138 pages of the Compound Index in the Ninth Collective Index of Chemical Abstracts are dedicated to this system. This review will concentrate on the more important recent developments of 1,3,5-triazine chemistry, and reference will be made to previous reviews, or typical papers, to illustrate the better-known aspects of the subject. 

There is an extensive literature on ammines and the Chemical Abstracts 10th Collective Index (1977-81) has four pages under this heading. One important parameter for this class of compound is the metal-nitrogen bond length and Table 1 lists some of the available data. Transition metal-NH, bond energies have also been calculated.100...
