A convenient enantioselective CBS-reduction of arylketones in flow

By on April 20th, 2018 in Flow chemistry

I spotted an exciting study about a sustainable, versatile, fast and environmentally friendly CBS-asymmetric reduction of aryl and heteroaryl ketones using flow technologies.

The researchers at the Department of Pharmacy (University of Bari, Italy) demonstrated handling of a borane solution safely and the switch to the use of 2-MeTHF as a greener alternative to traditional solvents. Another real benefit of using flow technology was that it allowed for a reduction of the amount of the chiral catalyst and avoided the use of an additive such as DEAN (N, N-diethylaniline). They used in-line FT-IR analysis for rapid reaction optimization and continuous aqueous work-up technologies enabled >90% recovery of the desired chloroalcohol.

Study details below – happy reading!
