摘要

建立了一种两步法合成氯丙醛环缩醛和无环缩醛的简易方法。它们很容易与正丁基锂反应生成稳定的丙醛缩醛结晶，而丙醛缩醛是强亲核试剂，可与氯三甲基硅烷、氯三甲基锡烷和氯甲酸甲酯反应，产率高，生成双官能团乙炔。

Preparative scalable method for the synthesis of cyclic and acyclic acetals of chloropropiolaldehyde and their transformation into acetals of lithiumpropiolaldehyde

A simple two-step and easily scalable method for the synthesis of cyclic and acyclic acetals of chloropropiolaldehyde was developed. They readily reacted with n-butyllithium to give stable crystalline acetals of lithiumpropiolaldehyde, which, being strong nucleophiles, reacted with chlorotrimethylsilane, chlorotrimethylstannane, and methyl chloroformate to form bifunctional acetylenes in high yields.
