A series of novel N-Bn-protected spirocyclic -proline esters were prepared using [3+2] cycloaddition and subsequently converted into their corresponding aldehydes. In addition, two novel N-Cbz-protected spirocyclic -proline esters were prepared using intramolecular cyclization starting from simple precursors.

New scaffolds for drugdiscovery, 6-azaspiro[4.3]alkanes, have been synthesized in two steps from four-membered-ring ketones: cyclobutanone, thienone, N-Boc-azetidinone (Boc = tert-butoxycarbonyl), etc. The key transformation was the reaction between electron-deficient exocyclic alkenes and an in-situ generated N-benzylazomethine ylide.

In the context of drug discovery, novel spirocyclic pyrrolidines have been synthesized in two steps from common three‐ to seven‐membered‐ring (hetero)alicyclicketones. The key transformation is a reaction between an electron‐deficient exocyclic alkene and an in situ generated N‐benzyl azomethine ylide. The developed method has been used to synthesize the central diamine core of the known antibacterial
