The [4 + 2] Addition of Singlet Oxygen to Thebaine:  New Access to Highly Functionalized Morphine Derivatives via Opioid Endoperoxides

, 2016
The photooxidation of thebaine (3) with a sun lamp affords two main products:  hydrodibenzofuran 10 (major) and benzofuran 11 (minor). The latter compound becomes predominant if a Hg lamp is used instead of a sun lamp. The formation of 10 proceeds via an
