Abstract
An efficient method for the preparation of arylnaphthalene lignans (ANLs) was developed, which is based on the Photo-Dehydro-Diels-Alder (PDDA) reaction. While intermolecular PDDA reactions turned out to be inefficient, the intramolecular variant using suberic acid as tether linking two aryl propiolic esters smoothly provided naphthalenophanes. The irradiations were performed with a previously developed annular continuous-flow reactor and UVB lamps. In this way, the natural products Alashinol D, Taiwanin C, and an unnamed ANL could be prepared.
