(Spectro-)electrochemical results demonstrate ligand-centred hydride ion-carrier capacity for a Rh(I) complex of a novel ‘non-innocent’ N-heterocyclic carbene ligand created by nicotinamide functionalisation.
Sterically controlled regioselectivelithiation of meta-halopyridocarboxamides derivatives using deuterated probes is described. A first experimental demonstration that the nitrogen is the main chelating-base approach site onto the oxazoline and N-alkoxyamide DMGs is reported.
[Structure: see text] Lithiation of 5-bromonicotinic acid protected as secondary or tertiary amide as well as (4,4'-dimethyl)oxazoline with lithium amides is reported. The unusual C-2 and C-4 regioselective lithiation of 3-bromo-5-(4,4'-dimethyl)oxazolinylpyridine using LTMP versus LDA was observed, providing a new route to substituted nicotinic acid scaffolds. The methodology was applied to the synthesis
