一般說明
Ethyl diazoacetoacetate is a diazo compound. It participates in Rh2(OAc)4-catalyzed reactions with arylalkylamines and diarylamines. Reaction of ethyl diazoacetoacetate with N-methyl pyrrole and pyrrole derivatives has been studied.
應用
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.

The Rh(2)(OAc)(4)-stabilized carbenoid derived from dimethyl diazomalonate has been found to insert into the N-H bond of sterically hindered secondary aliphatic amines to afford hindered tertiary aliphatic amines in quite satisfactory yields. For example dimethyl 2-(dicyclohexylamino)propanedioate was formed in 85%
