Abstract
Treatment of a diazo compound, i.e. a (diazomethyl)phosphonate or diazo(trimethylsilyl)methane, with a base, and subsequent alkenation of a carbonyl compound (Wittig–Horner reaction or Peterson elimination), followed by decomposition of the resulting diazoalkene affords an alkylidene carbene. This species may undergo intramolecular C—H insertion to generate five-membered carbocyclic or heterocyclic systems. In this chapter, some applications of this methodology in organic synthesis are reviewed.
