Development of Catalysts for the Stereoselective Hydrogenation of α,β-Unsaturated Ketones
摘要:
Iridium phosphinitoxazoline complexes were found to be new efficient catalysts for the asymmetric hydrogenation of arylated alpha,beta-unsaturated ketones. Linear as well as cyclic substrates are hydrogenated with similar success, giving selectivities of up to 99.7% ee.
