General description
Application
Ethyl diazoacetoacetate can be used as a reactant to synthesize:
- 1,4-oxathiocines and thiopyran derivatives via Rh-catalyzed reaction with 2-amino-4,5-dihydro-3-thiophenecarbonitriles.
- β-keto esters via C−H insertion reaction with aromatic aldehydes using NbCl5 as a catalyst.
- Diazoacetoacetate derivatives by reacting with aldehydes via aldol condensation and subsequent and in situ oxidation reaction.
- Isoquinolone and pyridone derivatives by Rh-catalyzed C−H activation/annulation reaction with various N-methoxybenzamides.
