By solving several crystal structures the authors of this Communication have found that the structure of compound 10 in Scheme 3 has been misassigned. It is not based on a β-lactame core as originally proposed but rather on the pyrrolidinedione scaffold 10′ which has the same molecular weight and a similar NMR spectrum as the proposed β-lactame. Therefore it is proposed that the cyclization of the intermediate Ugi product under the basic reaction conditions proceeds via the isocyanide-derived amide NH group and the ester moiety.
This correction does not affect the results and conclusions of the other compounds described in the communication. The authors sincerely apologize for this mistake.
