An efficient, practical, CoII‐catalyzed N‐acylation reaction of various amines using readily available and inexpensive DMF and other amides as carbonyl sources is described.
The present invention relates to novel indanyl urea derivatives, their pharmaceutically acceptable salts, and their isomers, stereoisomers, atropisomers, conformers, tautomers, polymorphs, hydrates and solvates. The present invention also encompasses process for preparing novel compounds and pharmaceutical composition of said compounds. The invention further relates to the use of the compounds for the preparation of medicament for use as pharmaceuticals.

the Mn(II)-catalyzed N-acylation of amines with high yields using N,N-dimethylformamide and other amides as the carbonyl source. The protocol is simple, does not require any acid, base, ligand, or other additives, and encompasses a broad substrate scope for primary, secondary, and heterocyclic amines. A practical protocol has been developed here for the Mn(II)-catalyzed N-acylation of amines with high
