Add time:07/27/2019 Source:sciencedirect.com
An asymmetric Michael addition of diphenylphosphine to β,γ-unsaturated α-keto esters was developed using a P-stereogenic pincer-Pd complex as a catalyst. The corresponding hydrophosphination products were obtained in good yields (up to 94%) and with moderate to good enantioselectivities (up to 93% ee) under the optimum reaction conditions.
