An article Photoelectrocyclization Reactions of Amidonaphthoquinones WOS:000526405900031 published article about BIOSYNTHESIS; RIFAMYCIN; ALKALOIDS; CLOSURE in [Yin, Jinya; Landward, Michael B.; Rainier, Jon D.] Univ Utah, Dept Chem, Salt Lake City, UT 84112 USA in 2020, Cited 31. COA of Formula: C5H8O2. The Name is (E)-2-Methylbut-2-enoic acid. Through research, I have a further understanding and discovery of 80-59-1
Readily available acrylamide naphthoquinones can be converted into the corresponding aza-anthraquinones using 6 pi-photoelectrocyclization reactions. Not only do these reactions not proceed thermally but, as demonstrated here, they can also be used to generate a range of aza-anthraquinone and aza-tetracycline derivatives including the natural products griffithazanone A and marcanine A. Several of the aza-anthraquinones generated in this work showed antibacterial activity.
