Please note! Course description is confirmed for two academic years (1.8.2018-31.7.2020), which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.


After the course the student will be able to

  • list effects contributing to regioselectivity & diastereoselectivity
  • describe shape and properties of frontier orbitals of typical organic functional groups
  • explain intramolecular interactions related to stereoelectronics
  • apply the concepts of control by polarity, orbital geometry, or sterics to predict the outcome of stereo- or regioselective reactions
  • propose suitable reagents or reaction conditions to selectively synthesize organic molecules with emphasis to position or relative configurations of functional groups

    The selective assembly of molecular structures in terms of positions or relative configurations of functional groups represents a crucial skill in modern organic synthesis, and a prerequisite in the production of fine chemicals, pharmaceuticals and agrochemicals.

    This course takes up previously reviewed organic transformations and discusses them in the context of regio- and diastereoselectivity. The Selectivity course will provide the tools to perform conformational analyses and employ general concepts such as polarity control and orbital control to predict reaction outcomes and relative configurations in C-C and C-heteroatom bond forming transformations. Reactions will include the addition of simple carbon nucleophiles, enolates and P-, S-, and Si-stabilized carbanions to carbonyls and olefinic double bonds as well as cycloadditions and rearrangements.
