Abstract
1. We have synthesized and proved the structure of the aminoketoesters formed by addition of secondary amines to acetylenic ketoesters. 2. Study of the PMR spectra of the aminoketoesters led to the conclusion that addition of secondary amine to the triple bond of acetylenic ketoesters leads to trans-isomers.
