Cover Picture: Asymmetric Organocatalyzed Phospha‐Michael Addition for the Direct Synthesis of Biologically Active Chromenylphosphonates (Adv. Synth. Catal. 19/2023)

The inside cover picture is an artistic illustration of the bifunctional activation of the phosphite and the iminochromene by a chiral squaramide tattooed on the arm of a chemist. Both substrates undergo the phospha‐Michael reaction described in the original article, enabling the chemist to have in hand enantioenriched chromenylphosphonates, an interesting family of bioactive compounds. The cover design is by I. G. Sonsona. Details can be found in the communication by Marqués‐López and Herrera and co‐workers (E. Marqués‐López, I. G. Sonsona, M. Garcés‐Marín, M. C. Gimeno, R. P. Herrera, Adv. Synth. Catal. 2023, 365, 3234–3240; DOI: 10.1002/adsc.202300563)
