The front cover picture , provided by Junling Zhao and co‐workers, illustrates an enantioselective Michael reaction of malononitrile to a‐substituted‐β‐nitroacrylates. This high efficient protocol was promoted by a cinchona alkaloid derived thiourea catalyst and the corresponding products, bearing quaternary chiral centers, were obtained in high yields and with high stereoselectivities. A dihydropyrrole derivative was readily obtained through Fe/HCl reduction of the product. Details can be found in the communication on pages 2437–2441 . (S. W. Chen, Q. X. Lou, Y. Y. Ding, S. S.
