General description

1-(Diethoxymethyl)imidazole is an orthoamide protected imidazole. The dianion reacts selectively at the 2 position[1][2] 1-(Diethoxymethyl)imidazole is a 1-substituted imidazoles.[3] Isoprene-mediated lithiation of 1-(diethoxymethyl)imidazole, leads to the preparation of the corresponding 2-lithio intermediate, which reacts with different electrophiles to afford 2-functionalised imidazoles.[3]

Application

1-(Diethoxymethyl)imidazole may be used in the preparation of various hydroxy- and amino-functionalized imidazoles, via isoprene-mediated lithiation followed by reaction with an electrophile.[4]
