壳聚糖气凝胶微球是一种从海洋甲壳类动物中获得的丰富的生物聚合物，已成功应用于催化水中的不对称羟醛反应，提供高产率、良好的立体选择性（高达 93% ee）和可回收性（高达 4 次运行）的产品。 DNP 和硬脂酸等添加剂对产量有有利的影响。
Aerogel microspheres of chitosan, an abundant biopolymer obtained from marine crustaceans, have been successfully applied to catalyze the asymmetric aldol reaction in water, providing the products in high yields and with good stereoselectivity (up to 93% ee) and recyclability (up to 4 runs). Yields were favourably affected by additives such as DNP and stearic acid.
