Golden touch: Gold-catalyzed reaction of N-sulfonyl hydroxylamines with terminal alkyne led to 3-pyrrolidinones by means of an oygen-transfer redox reaction. This protocol constitutes a direct method for forming α-amino carbonyl compounds. In sharp contrast, those with internal alkynes underwent 1,3-sulfonyl migration leading to 3-sulfonyl cyclic nitrones.
