One of the most interesting fields of mathematically oriented chemical
research is the so-called computer-assisted organic synthesis design.
These lecture notes elaborate the mathematical model of organic
chemistry, which offers formal concepts for unambiguous description of
computer algorithms for organic synthesis design including
retrosynthesis and reaction mechanisms. All definitions and theorems are
supplemented by many illustrative examples. The model is closely related
to the course of thinking of organic chemists. These notes will be
useful for all theoretically oriented organic chemists who are
interested in mathematical modelling of organic chemistry and
computer-assisted organic synthesis design.
