Abstract

This account summarizes recent developments in the ­nucleophilic addition reaction of diazo compound derived anion or enolate with electrophilic C=O and C=N bonds. Subsequent ­reaction of the addition products under transition-metal-catalyzed conditions, as well as their synthetic utility, are also presented.
