Evidence for an NIH shift in oxidation of naphthalene by the marine cyanobacterium Oscillatoria sp. strain JCM.

By M L Narro, C E Cerniglia, C Van Baalen and D T Gibson

Abstract

The marine cyanobacterium Oscillatoria sp. strain JCM oxidized naphthalene predominantly to 1-naphthol. Experiments with [1-2H]naphthalene and [2-2H]naphthalene indicated that 1-naphthol was formed with 68 and 74% retention of deuterium, respectively. No significant isotope effect was observed when the organism was incubated with a 1:1 mixture of naphthalene and [2H8]naphthalene. The results indicate that 1-naphthol is formed through a naphthalene 1,2-oxide intermediate, which rearranges spontaneously via an NIH shift mechanism
