Process for carbon-carbon bond formation at the C-4 position of 3-acylaminoazetidinones and products and starting materials therefor

The invention encompasses a process for stereoselective carbon-carbon bond formation at C-4 position of a 3-(acylamino)azetidinone. The process is carried out under free radical conditions using a (2-substituted or unsubstituted allyl)tin reagent. Also encompassed by the invention are certain 4-(substituted selenyl)azetidinone starting materials and the corresponding 4-(2'-substituted or unsubstituted allyl)-azetidinone products.
