Sulfonium ion-promoted traceless Schmidt reaction of alkyl azides

Schmidt reaction by sulfonium ions is described. General primary, secondary, and tertiary alkyl azides were converted to the corresponding carbonyl or imine compounds without any trace of the activators. This bond scission reaction through 1,2-migration of C-H and C-C bonds was accessible to the one-pot substitution reaction.

Ring Expansion of 2-Azido-2-phenyl-indan-1,3-dione for the Generation of Heterocyclic Scaffolds

A novel ring expansion based on the readily available 2-azido-2-phenyl-indan-1,3-dione is described. Treatment with primary amines and cesium carbonate in a two-step sequence gives rise to 3-amino-2,3-dihydroisoquinoline-1,4-diones with an unprecedented substitution pattern. The corresponding conversion using amino acid methyl esters leads directly to a novel tricyclic 1,10a-dihydroimidazo-isoquinoline-2,5,10-trione scaffold, a structure that has never been reported before, to the best of our knowledge.
