标题:Preparation Of 2-Substituted 4-Chloro-5-Formylimidazole And 5-Formylimidazole
摘要:该发明涉及一种2-取代-5-甲酰基咪唑的制备过程,其中方便地避免了在技术中已知的2-取代-4-羟甲基咪唑的中间高压合成,并且获得了更高的产率.相反,建议通过一锅法合成涉及2-取代-4-氯-5-甲酰基咪唑来制备这种2-取代-5-甲酰基咪唑,从而利用额外的去卤化步骤.此外,发现在制备过程中使用三氟甲磺酸盐催化剂可以显著提高2-取代-4-氯-5-甲酰基咪唑本身的产率和纯度.

标题:Preparation of 2-substituted 4-chloro-5-formylimidazoles by vilsmeier reaction of the condensation product of glycine and an imido ester with a formamide in the presence of a triflate (trifluormethanesulphonate) catalyst

摘要:The invention relates to a preparation process for 2-substituted 5-formylimidazoles, wherein the intermediate high-pressurized synthesis of an 2-substituted 4-hydroxymethylimidazole as known in the art is conveniently avoided, and wherein much higher yields are obtained. Instead, it is proposed to prepare such 2-substituted 5-formylimidazoles via a one-pot synthesis involving 2-substituted 4-chloro-5-formylimidazole, thereby employing an additional hydrodehalogenation step. Moreover, it is found that the yield and purity of 2-substituted 4-chloro-5-formylimidazole itself can be significantly improved using a triflate catalyst in the preparation process.
