A new facile method for the synthesis of 1-arylimidazole-5-carboxylates
摘要:
A new facile method for the preparation of 1-arylimidazole-5-carboxylates was developed. The new method involved reaction of anilines and ethyl glyoxylate in methanol to give alpha-anilino-alpha-methoxyacetates followed by cyclization with TosMIC, affording 1-arylimidazole-5-carboxylates in two steps in 40-94% overall yields.
