On March 31, 2022, Ho, Angel; Pounder, Austin; Koh, Samuel; Macleod, Matthew P.; Carlson, Emily; Tam, William published an article.Recommanded Product: Pentane-1,5-diol The title of the article was Acid-Catalyzed Intramolecular Ring-Opening Reactions of Cyclopropanated Oxabenzonorbornadienes with Carboxylic Acid Nucleophiles. And the article contained the following:
The present work demonstrates the ability of carboxylic acid tethered cyclopropanated oxabenzonorbornadienes (CPOBDs) to undergo ring-opening reactions in mild acidic conditions. The optimized reaction conditions involve the use of pTsOH in DCE at 90°C. Two regioisomers are formed but the reactions are highly regioselective towards type 3 ring-opened products. It was observed that substitution at the C5 and aryl positions of CPOBD significantly hinders the ring-opening reactions leading to decreased yields of ring-opened products, although high regioselectivity for the Type 3 ring-opened products is still maintained. Herein, the first examples of acid-catalyzed intramol. ring-opening reactions of CPOBD with carboxylic acid nucleophiles are reported. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Recommanded Product: Pentane-1,5-diol
