1. ChemInform Abstract: Rhodium(III)-Catalyzed Oxidative Bicyclization of 4-Arylbut-3-yn-1-amines with Internal Alkynes Through C-H Functionalization.

Author

Pi, Rui, Zhou, Ming‐Bo, Yang, Yuan, Gao, Cai, Song, Ren‐Jie, and Li, Jin‐Heng

Subjects
*PYRROLE derivatives, *RHODIUM catalysts, *AMINES, *CARBON-hydrogen bonds, *RING formation (Chemistry)
Abstract

A new Rh-catalyzed reaction of 4-arylbut-3-yn-1-amines (I) with symmetrically 1,2-disubstituted acetylenes (II) gives rise to cross-bicyclization products (III), whilst the use of unsymmetrically disubstituted alkynes (IV) leads to a mixture of regioisomers (V) and (VI). [ABSTRACT FROM AUTHOR]
