Catalyst-free intramolecular formal carbon insertion into σ-C-C bonds: a new approach toward phenanthrols and naphthols.

Abstract

The different reactivity of two kinds of carbonyl groups in keto aldehyde substrates has been exploited for the synthesis of phenanthrols, naphthols, and their heteroatom-containing analogues. Key to this highly efficient and robust methodology is the catalyst-free intramolecular formal diazo carbon insertion of N-tosylhydrazones into keto C-C bonds.
