On February 5, 2021, Liang, Ren-Xiao; Zhong, Chao; Liu, Zhi-Hong; Yang, Miao; Tang, Heng-Wei; Chen, Jian-Fei; Yang, Yun-Fang; Jia, Yi-Xia published an article.Product Details of 517-23-7 The title of the article was Enantioselective Arylation of Tetrasubstituted Enamines: Access to Enantioenriched Indolenine and 1H-Indole Derivatives. And the article contained the following:
Palladium-catalyzed intramol. enantioselective β-arylation of tetrasubstituted endocyclic and exocyclic enamines was developed. A range of optically active medium-ring fused indolenines or 3,3′-spiroindolenines were achieved in enantiomeric ratios up to 98:2 with Cs2CO3 or K3PO4 as the base in the presence of chiral PHOX ligands. The use of Ag3PO4 as a base led to enantioenriched 1H-indoles in good enantiomeric ratios (up to 89:11) with (S)-DIFLUORPHOS as a chiral ligand, which proceeded via a possible domino enamine-isomerization/β-arylation sequence. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Product Details of 517-23-7
