oxamination reactions of indolederivatives to afford functionalized spirocyclic products. These step-economical reactions, which involve C–N and C–O bond formation, feature mild conditions, a broad substrate scope, high yields, exclusive diastereoselectivity and step-economy. In addition, a similar protocol could be used to synthesize spirolactams by dearomative amidation of phenol derivatives.

3-methyl-N-(2'-phenylethyl)-butyramide, produced by a marine bacterium identified as Halobacillus salinus, inhibits QS controlled phenotypes in multiple Gram-negative reporter strains. Here we report that N-phenethyl hexanamide, a structurally-related compound produced by the marine bacterium Vibrio neptunius, similarly demonstrates QS inhibitory properties.
