Saccharin: an efficient organocatalyst for the one-pot synthesis of 4-amidocinnolines under metal and halogen-free conditions
A mild and efficient protocol for the one-pot synthesis of 4-amidocinnolines was developed using saccharin as a cheap and eco-friendly organocatalyst and t-butyl nitrite as a metal-free diazotization reagent. The current method has advantages such as cost effectiveness, use of the biodegradable reag...
