The first catalytic application of oxidized carbon nanotubes in a four-component synthesis of fused heterocycles

摘要

Multiwalled carbon nanotubes were oxidized and then utilized as new heterogeneous nanocatalyst for the efficient one-pot, four-component synthesis of pyrazolopyranopyrimidinones. This present strategy offers important advantages in terms of its simplicity, low catalyst loadings, catalyst recyclability, high product yields, and non-toxic nature.
