The 115 Years Old Multicomponent Bargellini Reaction: Perspectives and New Applications

Molecules, 2021
Despite its uniqueness, the Bargellini multicomponent reaction remains barely known by the most part of chemists. This can be ascribed to the fact that this transformation has not been adequately reviewed in the classic books of named reactions in ...
