compound introduction
原酰胺保护的咪唑。二价阴离子选择性地在 2 位反应 应用 1-(Diethoxymethyl)imidazole is an orthoamide protected imidazole. The dianion reacts selectively at the 2 position 1-(Diethoxymethyl)imidazole is a 1-substituted imidazoles. 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.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.
