✦ Synopsis


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-crystal X-ray analysis.
