We report the diastereoselective synthesis of novel spiropiperidine templates for use in SAR studies of β-secretase (BACE) inhibitors and also as versatile ligands for other receptor types. The overall synthetic approach stems from chiral starting material benzyl (S)-2-methyl-4-oxopiperidine-1-carboxylate and employs an Overmanrearrangement to control the stereochemistry at the quaternary center.
