2-Isopropylpyridine has been successfully metallated and functionalized by using potassium diisopropylamide (KDA). Subsequent functionalization has been achieved with a wide range of electrophiles and good to excellent yields have been obtained. The action of other potassium or sodium bases has also been investigated. (C) 1998 Elsevier Science Ltd. All rights reserved.

Air-stable and convenient amidobenziodoxolones as an amidating reagent were disclosed to enable direct amidation on a wide range of C(sp2)–H bonds of (hetero)arenes and alkenes, as well as unactivated C(sp3)–H bonds under RhIII catalysis. The approach to access 49 examples of structurally diverse amides is featured by mild conditions, complete chemoselectivity and regioselectivity, broad substrate scope
Disclosed are compounds, having the following structure, useful as inhibitors of Phosphodiesterase 1 (PDE1), compositions comprising the compounds, and methods of using the same.

Disclosed herein is a RhIII‐catalyzed chelation‐assisted activation of unreactive CH bonds, thus enabling an intermolecular amidation to provide a practical and step‐economic route to 2‐(pyridin‐2‐yl)ethanamine derivatives. Substrates with other N‐donor groups are also compatible with the amidation. This protocol proceeds at roomtemperature, has a relatively broad functional‐group tolerance and high
