These Corrections are as close as possible to the published version [see Pure Appl. Chem., 1999, 71, 1327-1330. Copyright IUPAC; reproduced with the permission of IUPAC]. If you need to cite these rules please quote this reference as their source. To assist readers for some corrections the corrected drawing has been added.
Among the names and structures used as examples in the 1993 Guide to IUPAC Nomenclature of Organic Compounds (Guide)  some errors  appear, several of which are likely to be quickly obvious and untroublesome. To reduce the possibility of confusion among users of the Guide, however, we publish a list of corrections here rather than waiting until a new edition of the Guide has been prepared. The on-line edition of the Guide has been corrected to correspond with this list. The formulae in this list that is intended to specify stereochemical information is drawn in the style recommended in the 1996 publication "Basic Terminology of Stereochemistry" .
