Aziridines are small three-membered heterocyclic compounds. They are important as building blocks for many nitrogen-containing biologically active compounds and as chiral ligands in metal catalyzed asymmetric synthesis of different organic compounds. In the first part of this thesis, we have studied the ring opening reactions of various racemic and chiral aziridine-2-phosphonates. Regioselective aziridine ring opening reaction with HCl formed -amino--chlorophosphonates in 60-95 % yield and the same reaction with alcohols in the presence of H2SO4 formed -amino--alkoxyphosphonates in 35-91 % yield. In the second part of this thesis, we have studied the catalytic performance of aziridine based chiral ligands with a transition metal for 1,3-dip...
