The generation of carbamoyl radicals, followed by their addition to heteroarenes, was performed under mild conditions through a metal-free photocatalyzed decarboxylation of oxamic acids. The process has been applied to the carbamoylation of heteroaromatic bases using α-aminoacid-derived oxamic acids, leading to the corresponding amides without racemization.
Synthesis of amino acid derived imidazolidinium salts as new NHC precatalysts

The preparation of new chiral symmetrically and unsymmetrically N,N′-disubstituted imidazolium based NHC salts Ib, IIb, IIIa-c and IVc-h from the amino acids l-proline and l-phenylalanine, is reported. Some preliminary tests have been carried out, demonstrating that the chiral NHCs give chiral induction in organometallic catalysis and can be used as organocatalysts.
