Stereoselective Addition of Grignard Reagents to New P-Chirogenic N-Phosphinoylbenzaldimines: Effect of the Phosphorus Substituents on the Stereoselectivity
give both diastereoisomers in high yields and with promising diastereomeric ratios. Then N-[(tert-butyl)(phenyl)phosphinoyl]benzaldimine, which displayed the best results, was subjected to the 1,2-addition of various Grignardreagents to evaluate the best chiral induction due to the stereogenic phosphorus atom. The corresponding adducts were obtained in excellent yields and with moderate to excellent diastereoisomeric
