Polycyclic derivatives incorporating a cyclopropyl group have been efficiently synthesized from propargyl acetates using platinum(II), gold(I) and gold(III) catalysis. These reactions which are also viable for the preparation of medium-sized rings, proceed with a complete diastereocontrol and can also be run in neat conditions.
使用铂(II),金(I)和金(III)催化,可从乙酸炔丙酯高效合成具有环丙基的多环衍生物。这些反应对于制备中型环也是可行的,可以进行完全的非对映控制,也可以在纯净条件下进行。
