Synthesis and application of stereogenic nitrogen-containing ammonium salts as phase-transfer catalysts

[摘要] The chirality of nitrogen was at the forefront of chemistry over 110 years ago. Since then it has been widely under-acknowledged as a potential chirality source in organic synthesis. This thesis demonstrates the diastereoselective formation of stereogenic nitrogen-containing ammonium salts. Over 150 compounds were synthesised and employed as phase-transfer catalysts in order to assess the chiral-at-nitrogen influence on the outcome of two common phase-transfer-catalysed reactions. Several X-ray crystal structures of single diastereoisomer chiral-at-nitrogen ammonium salts were isolated as well as the synthesis of a library of secondary and tertiary amines.
