1,3-Dienes are readily available feedstocks that are widely used in the laboratory and industry. However, the potential of converting 1,3-dienes into value-added products, especially chiral products, has not yet been fully exploited. By synergetic photoredox/copper catalysis, we achieve the first visible-light-induced, enantioselective carbocyanation of 1,3-dienes by using carboxylic acid derivatives
1,3-二烯是现成的原料,广泛用于实验室和工业。然而,将 1,3-二烯转化为高附加值产品,尤其是手性产品的潜力尚未得到充分开发。通过协同光氧化还原/铜催化,我们通过使用羧酸衍生物和三甲基甲硅烷基氰化物实现了 1,3-二烯的第一个可见光诱导的对映选择性碳氰化。在温和和中性的条件下,可以从实验室稳定且用户安全的化学品中以通常良好的效率和高对映选择性生产各种手性烯丙基氰化物。此外,初步结果还证实,这种成功可以扩展到 1,3-烯炔和 1,3-二烯和 1,3-烯炔的四组分羰基化碳氰化。
