Org Lett. 2018 Jul 6;20(13):3915-3918. doi: 10.1021/acs.orglett.8b01496. Epub 2018 Jun 26.

Abstract

A direct synthesis of tropones (2,4,6-cycloheptatrienes) from simple preorganized triynes has been elaborated. This simple rhodium-catalyzed domino strategy allows one-pot access to fully substituted tropones in a 6-6-7-5 tetracyclic core in average to high yields.
