I found the field of Chemistry very interesting. Saw the article Photoelectrocyclization Reactions of Amidonaphthoquinones published in 2020. Safety of (E)-2-Methylbut-2-enoic acid, Reprint Addresses Rainier, JD (corresponding author), Univ Utah, Dept Chem, Salt Lake City, UT 84112 USA.. The CAS is 80-59-1. Through research, I have a further understanding and discovery of (E)-2-Methylbut-2-enoic acid
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.
About (E)-2-Methylbut-2-enoic acid, If you have any questions, you can contact Yin, JY; Landward, MB; Rainier, JD or concate me.. Safety of (E)-2-Methylbut-2-enoic acid
