Abstract
This thesis describes the development of new methods for the synthesis of 1,2-
diamines. Chapter one reviews current methods for the synthesis of 1,2-
diamines, and their importance in chemistry. Chapter two highlights attempts to
synthesise 1,2-diamines using two nitrogen-containing heterocycles, namely 3-
phenyl-1,3,5-triazabicyclo[3.2.0]hept-6-ene-2,4-dione and imidazolin-2-one,
which both contain an endocyclic double bond. It includes the synthesis of a
novel 1,2-diazetine as well as the functionalisation of imidazolin-2-one via a
palladium-catalysed cross-coupling reaction with phenyl iodide. Subsequent
hydrogenation and hydrolysis was then utilised to afford 1-phenylethane-1,2-
diamine dihydrochloride. Chapter three describes the synthesis and
functionalisation of a range of 3-methylene-1,2-diazetidines that were
subsequently hydrogenated in an asymmetric fashion, with [Rh(NBD)2]BF4 and
ligand Mandyphos M004-1, to yield 1,2-diazetidines with up to 89% ee.
Reduction with LiDBB allowed for the synthesis of two carbamate-protected
1,2-diamines in three steps. The first examples of epoxidation, reaction with
tetracyanoethylene and 1,3-dipolar cycloadditions of 3-methylene-1,2-
diazetidines are reported. Chapter four details the experimental procedures and
characterisation data for the novel compounds produced.
