Quinazolin-dione-N-3-alklyl derivatives are the core scaffolds for several categories of bioactive small molecules, but current synthetic methods are costly, involve environmental hazards, and are not uniformly scalable. Here, we report an inexpensive, flexible, and scalable method for the one-pot synthesis of substituted quinazolin-dione-N-3-alkyls (isomers of isatoic-8-secondary amides (IASAs)) from
