A new approach to the synthesis of β-fluoropyrrole derivatives
摘要:
beta-Fluoropyrrole derivatives are synthesized in high yields by the reaction of alpha,alpha-difluoro-gamma-iodo-gamma-(electron-withdrawing-group)-substituted ketones and ammonium hydroxide at room temperature; providing a new, simple, and efficient method for the synthesis of beta-fluorinated pyrrole rings. A possible mechanism is proposed.
