Microwave-assisted flexible synthesis of 7-azaindoles
Schirok, Hartmut
, p. 5538 - 5545 (2007/10/03)
7-Azaindoles are versatile building blocks, especially in medicinal chemistry, where they serve as bioisosteres of indoles or purines. Herein, we are presenting a robust and flexible synthesis of 1,3- and 1,3,6-substituted 7-azaindoles starting from nicot
