α-Phosphanyl amino acids: Diphenylphosphanyl glycines with a chiral N-substituent

A facile one-pot three-component synthesis of chirally N-substituted phosphanylglycines is reported. 1d forms enantiopure crystals but in solution diastereoisomers are present by kinetic lability. With Ni(COD)2 ethylene oligomerization catalysts are formed.70
