The direct conversion of feedstock chemicals into value-added products is of broad interest in chemical research. Herein, we present a regioselective and diastereoselective three-component dialkylation of feedstock 1,3-dienes with Hantzsch esters and aldehydes for the synthesis of homoallylic alcohols. The reaction is enabled by dual photoredox and chromium catalysis and can also be performed enantioselectively by employing chromium-bisoxazoline complexes.

双光氧化还原和铬催化1,3-二烯的二烷基化

将原料化学品直接转化为增值产品在化学研究中引起了广泛的兴趣。在本文中，我们介绍了用Hantzsch酯和醛对原料1,3-二烯进行区域选择性和非对映选择性三组分二烷基化反应，以合成均烯丙基醇的方法。该反应通过双重光氧化还原和铬催化而实现，并且也可以通过使用铬-双恶唑啉络合物对映选择性地进行。
