hybrid materials for heterogeneous enantioselective organocatalyzed Michael addition reaction. Developed through the ready intercalation of α-amino acids and α,β-dipeptides into reconstructed hydrotalcite (Mg/Al) by means of sustainable technics such as mechanochemical and ultrasound activation. The conjugate addition of aldehydes to maleimides under mild and solvent free conditions proceeded with high
用于多相对映选择性有机催化迈克尔加成反应的可回收杂化材料。通过机械化学和超声活化等可持续技术,将 α-氨基酸和 α,β-二肽随时嵌入到重建的水滑石 (Mg/Al) 中而开发。在温和且无溶剂的条件下,醛与马来酰亚胺的共轭加成以高产率和优异的对映选择性高达 99 : 1 er 进行。
