Hantzsch esters were often previously used as reductants in thermal catalytic hydrogenation reactions. Over the last few decades, Hantzsch esters have proven to be a useful class of electron donors and proton sources in photoredox catalyzed processes. Moreover, under photoredox catalytic conditions, alkyl-1,4-dihydropyridines can serve as versatile types of alkylation reagents via oxidative fragmentation mechanisms. This minireview highlights the recent advances in the chemistry of Hantzsch esters in photoredox catalyzed organic synthesis, with particular emphasis placed on reaction mechanisms. We hope that this review will inspire further new reaction design and developments with such a class of readily accessible reagents.

Hantzsch酯：在光氧化还原催化的有机合成中新兴的一类通用试剂。

Hantzsch酯以前经常用作热催化氢化反应中的还原剂。在过去的几十年中，汉茨酯已被证明是光氧化还原催化过程中有用的一类电子供体和质子源。而且，在光氧化还原催化条件下，烷基1，4-二氢吡啶可通过氧化断裂机理用作多种类型的烷基化试剂。本篇综述着重介绍了汉茨酯在光氧化还原催化的有机合成中化学的最新进展，特别着重于反应机理。我们希望这篇综述将启发这类易获得的试剂的进一步的新反应设计和开发。
