A transition-metal-free sp3 C–H amination reaction has been established for imidazo[1,5-a]pyridine synthesis employing molecular iodine from 2-pyridyl ketones and alkylamines. In the presence of sodium acetate (NaOAc), the I2-mediated oxidative annulations of readily available substrates produced a variety of imidazo[1,5-a]pyridine derivatives efficiently in a one-pot manner. The present synthetic approach is operationally simple and can be conveniently carried out on a gram scale. Moreover, under the optimal reaction conditions a series of 1-(2-pyridyl)imidazo[1,5-a]pyridine cysteine protease inhibitors were easily prepared from the corresponding di-2-pyridyl ketones and substituted benzylamines in satisfactory yields.

Organic & Biomolecular Chemistry (OBC) publishes original and high impact research and reviews in organic chemistry. We welcome research that shows new or significantly improved protocols or methodologies in total synthesis, synthetic methodology or physical and theoretical organic chemistry as well as research that shows a significant advance in the organic chemistry or molecular design aspects of chemical biology, catalysis, supramolecular and macromolecular chemistry, theoretical chemistry, mechanism-oriented physical organic chemistry, medicinal chemistry or natural products. Articles published in the journal should report new work which makes a highly-significant impact in the field. Routine and incremental work is generally not suitable for publication in the journal. More details about key areas of our scope are below. In all cases authors should include in their article clear rationale for why their research has been carried out.
