Abstract: In the presence of ultrasonically dispersed potassium or his-quaternary ammonium salts, 2, 5-piperazinedione condenses with α,β-unsaturated aldenhydes. The stereochemistry of the pmducts. was confirmed and 1H chemical shifts of the products were assigned by sorts of spectroscopic and chemical methods.
