课题组的研究工作主要分为两大部分： 一、不对称有机催化合成 不对称有机催化是不对称催化研究领域中的一项新技术。自2000年以来，不对称有机催化以惊人的速度发展，被广泛用于合成天然产物及复杂的手性分子，也因此获得了2021年诺贝尔化学奖。课题组的主要工作是发现和阐明新的不对称有机催化过程，开发“完美的化学反应”，包括多种不同催化剂参与的联合催化等，以解决手性合成方法中未解决的问题。最终的目标是开发绿色环保和创新的催化方法，使其在现代有机合成中得到广泛应用。 环状缩醛或者缩醛胺结构广泛存在于天然产物以及具有生物活性的化合物结构中，并且往往对这个化合物的生物活性起着关键作用。它们可以作为药效团直接与生物靶标相互作用或者作为支架将侧链导向特定方向从而引起生物活性的改变。我们课题组一直致力于利用不对称有机催化合成多种结构类型的手性环状缩醛以及缩醛胺，包括并环，桥环以及螺环等。随后，对所得化合物进行生物活性筛选，包括抗肿瘤，抗病毒，抗炎，抗糖尿病，抗痛风以及精神类疾病等，以期获得先导物。
二、药物设计与合成 基于海洋来源活性化合物的结构特点，利用上述发展的不对称催化合成策略，对其进行结构改造，并深入研究构效关系，以提高药理活性，降低毒副作用，进而提高其成药性，为发现海洋来源的活性先导化合物并进行产业转化提供物质基础。我们课题组专注于结构中含有缩醛或者缩醛胺骨架的海洋来源的活性化合物，结合计算机辅助药物设计，以期获得活性更好的药物先导物。
