Tetrahedron: Asymmetry presents experimental or theoretical research results of outstanding significance and timeliness on asymmetry in organic, inorganic, organometallic and physical chemistry, as well as its application to related disciplines, especially bio-organic chemistry. The journal publishes critical reviews, original research articles and preliminary communications dealing with all aspects of the chemical, physical and theoretical properties of non-racemic organic and inorganic materials and processes. Topics relevant to the journal include: the physico-chemical and biological properties of enantiomers; strategies and methodologies of asymmetric synthesis; resolution; chirality recognition and enhancement; analytical techniques for assessing enantiomeric purity and the unambiguous determination of absolute configuration; and molecular graphics and modelling methods for interpreting and predicting asymmetric phenomena. Papers describing the synthesis or properties of non-racemic molecules will be required to include a separate statement in the form of a Stereochemistry Abstract, for publication in the same issue, of the criteria used for the assignment of configuration and enantiomeric purity. From 1996, Tetrahedron: Asymmetry is included in Tetrahedron Alert, the first phase of the Tetrahedron Information System. Tetrahedron Alert is the new electronic information service accessible via the Internet, and is a pre-publication service which provides the contents lists and graphical abstracts of current and forthcoming issues for all 5 of the Tetrahedron journals. Updated weekly Tetrahedron Alert offers: the option to view the contents list as graphical abstracts; the ability to search a single journal or across all 5 journals; search options using user-friendly query forms; hypertext links to facilitate navigation; the facility to print to your own printer. At any given time, Tetrahedron Alert contains approximately 3-4 months worth of current issues and accepted papers. A sampler which demonstrates the content and functionality of Tetrahedron Alert can be accessed via the Tetrahedron Information System Home Page at http://www.elsevier.nl/locate/tis.
