aldehydes via the iodoformylation of terminal alkynes with TMSCF3 and NaI. This synthetic method uses inexpensive and easy-to-handle chemical feedstocks and employs a commercially available CuI catalyst. It can transform a broad range of terminal alkynes into bis-electrophile (E)-β-iodo-α,β-unsaturated aldehydes with excellent chemoselectivity, regioselectivity, and stereoselectivity. Moreover, it
在此,我们描述了一种通过末端炔烃与 TMSCF 3和 NaI的碘甲酰化合成 ( E )-β-碘-α,β-不饱和醛的方法。这种合成方法使用廉价且易于处理的化学原料,并采用市售的 CuI 催化剂。它可以将多种末端炔烃转化为具有优异化学选择性、区域选择性和立体选择性的双亲电子( E )-β-碘-α,β-不饱和醛。此外,证明该协议具有丰富的有机反应性。
