Heaney, Frances; Bourke, Sharon; Burke, Cathriona; Cunningham, Desmond; McArdle, Patrick (Royal Society of Chemistry (RSC), 1998-01-01)Synthesis of the title ring system by a sequential intermolecular nucleophilic displacement and intramolecular 'conjugate' addition has been achieved both as a one pot and as a stepwise procedure; an X-ray structure ... -
Pyrimidine annelated heterocycles - synthesis and cycloaddition of the first pyrimido[1,4]diazepine n-oxides
Heaney, Frances; Burke, Cathriona; Cunningham, Desmond; McArdle, Patrick (Royal Society of Chemistry (RSC), 2001-01-01)5-Formyl- and 5-acetyl-4-(alkenylamino)pyrimidines 5 have been prepared as precursors to novel pyrimido[1,4]diazepine N-oxides 3. In addition to cyclisation to the targeted dipoles the substrates 5 have also been observed ...
