Decarboxylative cross-coupling of aliphatic acid anhydrides with vinyl triflates or halides was accomplished via nickel catalysis. This methodology works well with a broad array of substrates and features abundant functional group tolerance. Notably, our approach addresses the issue of safe and environmental installation of methyl or ethyl group into molecular scaffolds. The method possesses high chemoselectivity

Disclosed herein is a method for making compounds that are useful as caspase inhibitor prodrugs of formula I:
1
wherein R
1
is an optionally substituted group selected from an aliphatic group, aralkyl group, heterocyclylalkyl group or aryl group, and R
2
is preferably a P
2
-P
4
moiety of a caspase inhibitor. Key intermediates include the azidolactones III and VIII:
