Radical decomposition of bis((2S)-N-benzyloxycarbonyl-2-aminopentan-5-carboxy-1-methyl ester)iodobenzene followed by decarboxylation and subsequent conjugate addition with a series of selectively protected dehydroamino acids leads to new analogues of diaminopimelic acid.

The cyclic methylene compounds (1)–(3) undergo diastereoselective free radicaladdition when treated with alkylmercury hydride or alkyl iodide/tributylstannane to give products useful for the enantioselective synthesis of α-amino and α-hydroxy acids.
