Beckmann rearrangement was used as a key step to synthesize six-membered lactams fused to a heteroaromatic or aromatic system. Derivatives of biologically active scaffolds like β-and γ-carbolinone, dihydropyrrolopyridinone and tetrahydroisoquinolinone were synthesized using this strategy.
Indole derivatives R 0140Thermal and Microwave-Assisted Conjugate Additions of Indole on Electron--Deficient Nitro-Olefins. -The microwave-assisted conjugate addition of indole (I) to electron-deficient nitro-olefins (II) leads to significantly higher yields and proceeds much faster compared to classical methods such as heating in a sealed tube or via Grignard reaction. -(KUSURKAR*, R.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
