The Synthesis and analysis of methaqualone and some positional structural isomers thereof

Van Zyl, Etienne Francois (University of Pretoria, 2006-11-30)

An extensive review of the reported synthesis of methaqualone (2-methyl-3-ο-tolyl-4(3H)-quinazolinone) and some positional and structural isomers of methaqualone is given. A detailed summary of the synthetic routes reviewed ...
Synthetic applications of bicyclic phosphoric triamides

Pienaar, Danie (University of Pretoria, 2007-11-17)

Bis(2-arylaminoethyl)amines cannot be efficiently prepared by the obvious route from bis(2-chloroethyl)amine and anilines, as intramolecular cyclisation to piperazine is favoured over a second substitution to form the open ...
X-ray and NMR spectropscopic studies of selected heterocyclic compounds of phosphorus and nitrogen

Mampa, Richard Mokome (University of Pretoria, 2007-02-13)

A full IH, l3C and 31P NMR assignments of phosphoric triamides 1-oxo-2,8-diphenyl-2,5,8-triaza-l-phosphabicyclo [3.3.0]octane (1), l-oxo-lO-phenyl-4,7,lO-triaza-2.3-benzo-l-phoshabicyclo [5.3.0]decane (2) and 1-oxo-4,7,l ...
