Pharmaceutical intermediate
Serves as an intermediate in the multi-step synthesis of active pharmaceutical ingredients and candidate molecules. The reactive nitrile and protected lactam allow controlled downstream functionalisation.
Heterocyclic building block
The fused pyrido[2,3-b][1,4]oxazinone scaffold is a useful core for constructing nitrogen- and oxygen-containing heterocyclic libraries. It is well suited to medicinal-chemistry and discovery programmes.
Medicinal-chemistry research
Employed in structure-activity relationship studies where the methoxybenzyl group and carbonitrile provide distinct points for analogue generation. Supports exploratory and lead-optimisation work.
Nitrile-based further synthesis
The 6-carbonitrile can be transformed by established chemistry into amides, carboxylic acids, amidines, tetrazoles or amines, broadening access to related derivatives for laboratory programmes.
