In 2022,Zhang, Di; Xiong, Youyuan; Guo, Yingjie; Zhang, Lei; Wang, Zheng; Ding, Kuiling published an article in Chemistry – A European Journal. The title of the article was 《Palladium-Catalyzed Enantioselective Intramolecular Heck Carbonylation Reactions: Asymmetric Synthesis of 2-Oxindole Ynones and Carboxylic Acids》.HPLC of Formula: 63069-48-7 The author mentioned the following in the article:
A Pd-catalyzed enantioselective domino Heck carbonylation reaction of o-iodoacrylanilides with terminal alkynes and water as the nucleophiles was discussed and afforded a diversity of β-carbonylated 2-oxindole derivatives bearing a 3,3-disubstituted all-carbon quaternary stereocenter, in high yields (55-99%) with good to excellent enantioselectivities (up to 99% ee). The synthetic utilities of the protocol was demonstrated in the gram-scale synthesis of 2-oxindole-derived ynone and carboxylic acid, as well as the facile synthesis of chiral 2-oxindoles with a pyrazole or isoxazole moiety. The experimental part of the paper was very detailed, including the reaction process of 4-Chloro-2-iodoaniline(cas: 63069-48-7HPLC of Formula: 63069-48-7)
4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Reduction of nitro compounds, RNO2, by hydrogen or other reducing agents produces primary amines cleanly (i.e., without a mixture of products), but the method is mostly used for aromatic amines because of the limited availability of aliphatic nitro compounds. Reduction of nitriles and oximes (R2C=NOH) also yields primary amines.HPLC of Formula: 63069-48-7
