Highly stereoselective synthesis of cyclopropylphosphonates catalyzed by chiral Ru(II)-Pheox complex. | LitMetric

Highly stereoselective synthesis of cyclopropylphosphonates catalyzed by chiral Ru(II)-Pheox complex.

Org Lett

Department of Environmental and Life Sciences, Toyohashi University of Technology, 1-1 Hibarigaoka, Tempaku-cho, Toyohashi 441-8580, Japan.

Published: June 2014

Ru(II)-Pheox-catalyzed asymmetric cyclopropanation of diethyl diazomethylphosphonate with alkenes, including α,β-unsaturated carbonyl compounds, afforded the corresponding optically active cyclopropylphosphonates in high yields and with excellent diastereoselectivity (up to 99:1) and enantioselectivity (up to 99% ee).
