Some new, interesting, and unknown heterocyclic rings and open-chain molecules have been obtained with ease and under mild conditions by reaction of a wide range of amino carbonyl compounds with acetylenic esters. The reactivity is highly dependent on the substituents and their positions in the starting material, which can be either cyclic (pyrazolones) or open-chain compounds.
一些新的、有趣的和未知的杂环和开链分子已经通过广泛的氨基羰基化合物与炔酸酯的反应在温和的条件下轻松获得。反应性高度依赖于取代基及其在原料中的位置,原料可以是环状(吡唑啉酮)或开链化合物。
