Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. In an article, author is Wang, Si-Qing, once mentioned the application of 10500-57-9, Formula: C9H11N, Name is 5,6,7,8-Tetrahydroquinoline, molecular formula is C9H11N, molecular weight is 133.19, MDL number is MFCD00006734, category is quinoxaline. Now introduce a scientific discovery about this category.
Copper(I)-Catalyzed Asymmetric Vinylogous Aldol-Type Reaction of Allylazaarenes
A vinylogous aldol-type reaction of allylazaarenes and aldehydes is disclosed that affords a series of chiral gamma-hydroxyl-alpha,beta-unsaturated azaarenes in moderate to excellent yields with high to excellent regio- and enantioselectivities. With (R,R-P)-TANIAPHOS and (R,R)-QUINOXP* as the ligand, the carbon-carbon double bond in the products is generated in (E)-form. With (R)-DTBM-SEGPHOS as the ligand, (Z)-form carbon-carbon double bond is formed in the major product. In this vinylogous reaction, aromatic, alpha,beta-unsaturated, and aliphatic aldehydes are competent substrates. Moreover, a variety of azaarenes, such as pyrimidine, pyridine, pyrazine, quinoline, quinoxaline, quinazoline, and benzo[d]imidazole are well-tolerated. At last, the chiral vinylogous product is demonstrated as a suitable Michael acceptor towards CuI-catalyzed nucleophilic addition with organomagnesium reagents.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 10500-57-9 help many people in the next few years. Formula: C9H11N.
