Synthesis of 4-​aminotetrahydropyran scaffolds for drug discovery

Andrew Nortcliffe, Gavin D.S. Milne, Daniel Hamza, Christopher J. Moody


Functionalised tetrahydropyran scaffolds were prepared using a tethered enol-ether Prins cyclisation and elaborated to show their potential use in library synthesis. The key 4-hydroxytetrahydropyran scaffold could be readily manipulated to the 4-azidotetrahydropyran that could be elaborated via copper catalysed azide-alkyne cycloaddition or by reduction to the amine, to provide sp3-rich scaffolds useful for drug discovery.
