Zhang, Fangming published the artcileRh(III)-catalyzed regioselective C-H activation dialkenylation/annulation cascade for rapid access to 6H-isoindolo[2,1-a]indole, Category: benzothiophene, the main research area is isoindoloindole preparation regioselective diastereoselective; aryl indole acrylate dialkenylation cyclization tandem rhodium catalyst.
The 6H-isoindolo[2,1-a]indoles I [R = H, 2-Br, 2-NO2, 1,3-(CH3)2; R1 = H, 9-Me, 8-OMe, 8-F, etc.; R2 = Et, Me, n-Bu, t-Bu, Bn] and II were accessed via a Rh(III)-catalyzed N-H free indole directed C-H activation dialkenylation/annulation cascade in moderate to excellent yields. This protocol also features: reaction procedures that are insensitive to air and moisture, excellent regioselectivity and good functional group tolerance.
RSC Advances published new progress about Alkenylation (stereo-, regioselective). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Category: benzothiophene.
