Abstract
[reaction: see text] Addition of mixed alkynylzinc reagents to various arylimines is catalyzed by chiral amino acid-based ligand 1 and Zr(Oi-Pr)(4).HOi-Pr to afford chiral propargylamines in up to 90% ee. Oxidative removal of the o-anisidyl group affords the free amine, which can then be acylated.
摘要
[反应：见正文] 手性氨基酸基配体1和Zr(Oi-Pr)₄·HOi-Pr催化混合炔基锌试剂与各种芳基亚胺加成，得到对映体过量高达90%的手性炔丙胺。邻甲氧基苄基的氧化去除得到游离胺，然后可将其酰化。
