Ethyl 2-({6-amino-2-(benzylsulfanyl)-5-[2-(ethoxycarbonyl)prop-2-enyl]pyrimidin-4-yloxy}methyl)acrylate
A new synthesis of carbon-carbon bonds at the 5-position of 2-thiosubstituted pyrimidines via the Claisen rearrangement is reported. A direct route towards the synthesis of carbon bonds at the 5-position of 2-thiobenzyl pyrimidines when reacted with ethyl 2-(bromomethyl)acrylate at 328 K delivered the unexpected title compound, C23H27N3O5S. Structural elucidation showed this compound to have undergone O-allylation followed by ortho-Claisen rearrangement and subsequent secondary O-allylation with excess ethyl 2-(bromomethyl)acrylate. Disorder about the centre of symmetry allows it to exist as two conformers with different orientations of the phenyl group
Identification and development of the 1,4-benzodiazepin-2-one and quinazoline-2,4-dione scaffolds as submicromolar inhibitors of HAT
A library of 1,4-benzodiazepines has been synthesised and evaluated for activity against Trypanosoma brucei, a causative parasite of Human African Trypanosomiasis (HAT). The most potent of these derivatives has an MIC value of 0.97 μM. Herein we report the design, synthesis and biological evaluation of the abovementioned compounds
