Tandem C–O and C–N Bonds Formation Through O-Arylation and [3,3]-Rearrangement by Diaryliodonium Salts: Synthesis of N-Aryl Benzo[1,2,3]triazin-4(1H)-one Derivatives
摘要:
Metal-free O-arylation and [3, 3]-rearrangement have been shown as an efficient strategy to construct new C-O and C-N bonds in one-pot reactions. The method was used to prepare N-aryl benzo[1,2,3]triazin-4(1H)-one derivatives in good yields from N-hydroxy benzo[1,2,3]triazin-4(3H)-one and diaryliodonium salts. The reaction was tolerated a variety of sensitive functional groups such as iodine, nitro, ester, and aldehyde groups. A rational mechanism was proposed based on the experimental results, and the reaction was easily up to gram scale.

The present invention relates to the use of a compound of formula I as a coupling reagent in forming amide or ester bonds from a reaction between a carboxylic acid and an amine or an alcohol, respectively. The compounds of formula I are especially useful as coupling reagents in the preparation of peptide bonds during peptide synthesis. In particular, the compounds of formula I are useful in promoting the formation of reactive reaction intermediates, inhibiting side reactions and in suppression of racemization. In addition, the present invention provides novel compounds of Formula I, and salts of N-oxides thereof.
