STRUCTURE REACTION TYPE PARADIGM IN THE CONVENTIONAL METHODS OF DESCRIBING ORGANIC-REACTIONS AND THE CONCEPT OF IMAGINARY TRANSITION STRUCTURES OVERCOMING THIS PARADIGM

The description of organic reactions is discussed from the viewpoint of a sructure-reaction type (SRT) paradigm, in which structural information and reaction type are stored and manipulated more or less independently. This paradigm must be overcome in order to construct an integrated system that will support both retrieval of organic reactions and synthetic design. The concept of imaginary transition structures (ITS) is introduced as a unitary representation free from the SRT paradigm.
