A robust allylic palladium-NHC complex was developed and exhibited extremely high catalytic activity toward aminocarbonylation of various (hetero)aryl iodides under atmospheric carbon monoxide pressure, in which a broad range of secondary and primary amines were well tolerated. In addition, the concise synthesis of an anticancer drug tamibarotene was accomplished even in a gram scale, further highlighting the practical applicability of the protocol.

The synthesis of 2‐azido‐1‐benzoylindolin‐3‐yl2‐benzamidobenzoate commencing from (1H‐indol‐1‐yl)(phenyl)methanone and trimethylsilyl azide (TMSN3) under oxygen atmosphere is described in this paper. This transformation proceeds via a sequential dearomatization and ring‐opening cascade reaction of indoles in a cascade manner.

A novel one-pot synthesis of N-acylindoles via tandem cycloalkylation-annelation is described. This approach is based on the use of a strong solid-acid catalyst, montmorillonite K-10, and microwave irradiation under solvent-free conditions. The tandem cycloalkylation of amides and annelation of intermediate pyrroles were completed in minutes and provided good yields with high selectivities for the
