发现了 2-吡啶甲醛和 γ-羟基-α,β-乙炔酯之间形成高度功能化的环状缩醛的新转化。这种转变在非常温和的条件下进行,无需任何添加剂,并由吡啶环的碱性性质促进。
A new transformation between 2-pyridinecarboxyaldehyde and γ-hydroxy-α,β-acetylenic esters to form highly functionalized cyclic acetals was discovered. This transformation proceeds under very mild conditions without any additives and is promoted by the basic nature of the pyridine ring.
