Here we report the asymmetric Friedel-Crafts reaction between compounds α-aryl-α-fluoro-1,3-indanediones and indoles, catalyzed by an efficient chiral phosphoric acid catalyst. Using this methodology, a series of cyclic β-fluoroalcohols bearing two adjacent chiral centers were synthesized in up to 95% yield, with excel...

7-membered spirobenzazepinoindole frameworks constitute an important family of heterocyclic skeletons with broad utility in pharmaceutical research. Despite their value, the stereoselective synthetic routes toward chiral gem-difluorinated spirobenzazepinoindoles remain unexplored, and a general, efficient constructio...
