We describe here the first synthesis of N-phosphoryl ynamides featuring C- and P-chirality via copper(I)-catalyzed amidative cross-couplings between phosphoramidates and phosphordiamidates with alkynyl bromides. Also featured is a tandem aza-Claisen–hetero-[2 + 2] cycloaddition for the synthesis of N-phosphoryl azetidin-2-imines.
