The preparative aspects of the addition of nucleophiles to alkyne-derivatives having both push- and pull-groups (1) are discussed: The addition of primary and secondary amines as well of aliphatic alcohols to the alkyne-derivatives 1 in most cases predominantly yields the Michael-adducts 2–10. The importance of a side-reaction consisting in an addition of amines to C(2) of the alkyne-derivatives 1
讨论了将亲核试剂添加到同时具有推基和拉基的炔烃衍生物中的制备方面(1):在大多数情况下,向炔烃衍生物1中添加伯胺和仲胺以及脂肪族醇主要产生迈克尔-加成物2 – 10。包括在加成胺的至C(2)的炔衍生物的副反应的重要性1个增加该系列1C « 1B < 1A和由立体电子效应控制。化合物的光谱性质2 - 10中给出。
