The preparation of conformationally hindered molecules and their study by DNMR and computational methods are my thesis’s core.
In the first chapter, the conformations and the stereodynamics of symmetrically ortho-disubstituted aryl carbinols and aryl ethers are described.
In the second chapter, the structures of axially chiral atropisomers of hindered biphenyl carbinols are studied.
In the third chapter, the steric barriers and the -barrier of 1,8-di-aylbiphenylenes are determined.
Interesting atropisomers are found in the cases of arylanthrones, arylanthraquinones and arylanthracenes and are reported in the fourth chapter.
By the combined use of dynamic NMR, ECD spectroscopy and DFT computations, the conformations and the absolute configurations of 2-Naphthylalkylsulfoxides are studied in the fifth chapter.
In the last chapter, a new synthetic route to ,’-arylated secondary or tertiary alcohols by lithiated O-benzyl-carbamates carrying an N-aryl substituent and DFT calculations to determinate the cyclic intermediate are reported. This work was done in the research group of Prof. Jonathan Clayden, at the University of Manchester.
