Abstract

Organocatalysts play pivotal roles in accomplishing a wide range of useful organic transformations, and organocatalytic reactions are now becoming powerful tools in the construction of simple to complex molecular scaffolds. This remarkable field is growing rapidly with new concepts and designs. During the recent past, triethylamine (or N,N-diethylethanamine), has emerged as an efficient organocatalyst in carrying out so many organic transformations, thereby producing interesting molecular frameworks. Triethylamine is relatively safe, commercially available and cheap. This review offers a decade update on the developments of triethylamine-catalyzed organic transformations reported during the period of 2008 through 2017.
