## Abstract Aromatic amine phosphonato esters **4a–d** were obtained in excellent yields from the 1:1:1 addition reaction between triphenyl phosphite and dimethyl acetylenedicarboxylate in the presence of NH‐aromatic amines such as 2‐aminobenzophenone, 2‐aminoacetophenon, methyl‐2‐aminobenzoate, an
The reaction of 4-iodomethylazetidin-2-one ( 2) with the t-butyl ester of propioZic acid (4) in the presence both of equimolar amounts of copper(I) and oxygen results unexpected-Zy in the formation of the $-Zactum ynamide 5. Its structure was suggested by spectroscopic data and confirmed by singLe-c
