The present invention provides a concise synthetic method for generating lactam-fused beta-lactones that feature, in some embodiments, a tertiary fused carbinol, quaternary carbons, and a reactive beta-lactone moiety available for further reactions. The present invention further provides compounds synthesized by this method as well as methods of using these compounds as inhibitors of the proteasome and fatty acid synthase.

The syntheses of a series of enantiomerically pure C2-symmetric 4-(pyrrolidino)pyridine (PPY) derivatives by SNAr of 4-halo-/4-phenoxypyridines and by cyclocondensation from 4-aminopyridine are described. Preliminary results pertaining to their use as catalysts for acylative kinetic resolution of 1-phenylethanol are also presented. A single-crystal X-ray analysis of PPY If is reported.
