The Cover Feature shows the merging of chiral organic catalysts with inorganic materials, which gives rise to an hybrid organic–inorganic catalytic system able to catalyze the Michael addition of α,α-disubstituted aldehydes to maleimides under solvent free reaction conditions. The recovery, reusability and environmentally friendly conditions are represented by the illustrated landscape. More information can be found in the Full Paper by J. M. Landeros, E. Juaristi et al.

封面特征：插入水滑石中的 α-氨基酸和 α,β-二肽：醛与 N-取代马来酰亚胺的不对称迈克尔加成反应中的有效催化剂（Eur. J. Org. Chem. 37/2021）

Cover Feature展示了手性有机催化剂与无机材料的融合，产生了一种混合有机-无机催化体系，能够在无溶剂反应条件下催化 α,α-二取代醛与马来酰亚胺的迈克尔加成。恢复性、可重复使用性和环境友好条件由插图景观代表。更多信息可以在 JM Landeros、E. Juaristi 等人的全文中找到。
