Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Article, Chemical Communications (Cambridge, United Kingdom) called A Au(I)-catalyzed hydrogen bond-directed tandem strategy to synthesize indeno-chromen-4-one and indeno-quinolin-4-one derivatives, Author is Jiang, Chongguo; Xiong, Zhiling; Jin, Shengfei; Gao, Peng; Tang, Yingzhan; Wang, Yanshi; Du, Chuan; Wang, Xiaoyu; Liu, Yang; Lin, Bin; Liu, Yongxiang; Cheng, Maosheng, which mentions a compound: 20028-53-9, SMILESS is NC1=CC=C(Cl)C=C1C=O, Molecular C7H6ClNO, Recommanded Product: 2-Amino-5-chlorobenzaldehyde.
A gold-catalyzed hydrogen bond-directed tandem cyclization strategy to synthesize indeno-chromen-4-one and indeno-quinolin-4-one derivatives was developed. The hydrogen bond existing between the hydroxyl group (or the amide group) and the carbonyl group played an essential role in controlling the selectivity, which was confirmed by both exptl. and theor. evidence.
Compound(20028-53-9)Recommanded Product: 2-Amino-5-chlorobenzaldehyde received a lot of attention, and I have introduced some compounds in other articles, similar to this compound(2-Amino-5-chlorobenzaldehyde), if you are interested, you can check out my other related articles.
