Abstract
A novel method for the selective synthesis of (Z)-1,5-dien-2-yl esters has been developed though Pt(II)-catalyzed tandem 1,2-acyl and 1,2-hydride migration, along with an allyl migration reaction of propargylic carboxylates with electronically unbiased internal alkynes. The unusual selectivity of 1,2-acyloxy migration was realized.
摘要
通过铂（II）催化的串联1,2-酰基和1,2-氢化物迁移，以及炔丙基羧酸盐与电子中性的内炔的烯丙基迁移反应，开发了一种选择性合成（Z）-1,5-二烯-2-基酯的新方法。实现了1,2-酰氧基迁移的异常选择性。
