Asymmetric Organocatalyzed Phospha‐Michael Addition for the Direct Synthesis of Biologically Active Chromenylphosphonates

open access: yesAdvanced Synthesis &Catalysis, Volume 365, Issue 19, Page 3234-3240, October 13, 2023., 2023
Abstract The potential of phosphites as nucleophiles for the asymmetric synthesis of chiral chromene derivatives has been overlooked in the literature. Herein, we report a promising approach via asymmetric organocatalyzed phospha‐Michael addition to iminochromenes, using a bifunctional squaramide, which gives access to chromenylphosphonates, an ...
