Abstract 1°-Iodo esters, ketones, and nitriles react smoothly in atom transfer addition reactions with alkyl- substituted (nucleophilic) alkynes, but a 3°-iodoester prefers to add to ester-substituted (electrophilic) alkynes. These atom transfer additions are suited for preparing precursors for radical translocation reactions as well for appending β- lactam side chains.

Abstract The synthesis of 2-[(4-fluorophenylsulfonyl)methyl] carbapenem carboxylate 20 is described. The key step is a base mediated addition-elimination ring closure of a iodovinyl sulfone 12.
