Addition of α-Lithiated Nitriles to Azaheterocycles
摘要:
The addition of alpha-deprotonated nitriles to azaheterocycles followed by rearomatization is described. A simple two-step, one-pot procedure for the sequence is also presented.

Herein, we report a mild, operationally simple method for MinisciC–H acetylation of N-heteroarenes using vinyl ethers as robust, inexpensive acetyl sources. The reactions do not require a conventional photocatalysis, electrocatalysis, metal catalysis, light activation, or high temperature. This method is thus significantly more sustainable than previously reported methods in terms of cost, reagent
