Visible-Light-Triggered Difluoroacetylation/Cyclization of Chromone-Tethered Alkenes Enabling Synthesis of Tetrahydroxanthones

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(8), С. 5619 - 5633

Опубликована: Апрель 5, 2024

Hydroxanthones have attracted considerable attention due to their significance in organic and biological chemistry, yet synthesis remains a great challenge. In this study, series of chromone-tethered alkenes are designed, radical cyclization reaction these chromone derivatives has been achieved under photoredox conditions. The uses bromodifluoroacetamides or bromodifluoroacetates as coupling partners, affording broad range functionalized tetrahydroxanthone products with up 85% yields. is triggered via the generation difluoroacetate radicals alkene cations fac-Ir(ppy)3 2,3,5,6-tetrakis(carbazol-9-yl)-1,4-dicyanobenzene photocatalyst. This approach offers access various from readily available starting materials enriches research content heteroarene-tethered alkenes.
