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

a unique strategy to access multifunctional N-fused tricycles from α,β-unsaturated isoquinoline ketone and sulfonamide under mild reaction conditions. The methodology features wide substrate tolerance, and a set of N-fused heteroarenes including quinoline, phthalazine, quinazoline, quinoxaline, and benzothiazole cores are furnished efficiently. Moreover, the protocol is easy to scale up to synthesize
