The main problem with allopumiliotoxin synthesis arises from the alkylidene side chain because the stereochemistry of it can be difficult to control by Wittig-type functionalizations.
Dirigent protein, a class of proteins which dictate the stereochemistry of a compound synthesized by other enzymes
Gauche effect, in stereochemistry, a characterization in which the gauche rotamer which is more stable than the anti rotamer
The concept of intimate ion pairs is used to explain the slight tendency for inversion of stereochemistry during an SN1 reaction.
NMR database method, a strategy to identify the stereochemistry of certain chiral compounds
Kuhn's areas of study included: investigations of theoretical problems of organic chemistry (stereochemistry of aliphatic and aromatic compounds; syntheses of polyenes and cumulenes; constitution and colour; the acidity of hydrocarbons), as well as extensive fields in biochemistry (carotenoids; flavins; vitamins and enzymes).
