European Journal of Organic Chemistry, EarlyView.A multicomponent carbonylative Suzuki–Miyaura reaction was developed for the synthesis of C‐acyl glycosides. Using Pyridine‐Enhanced Precatalyst Preparation, Stabilization, and Initiation (PEPPSI‐IPr) catalysis and Mo(CO)6 as a solid CO source, the reaction enables selective carbonylation of three components in synthetically useful yields, providing a ...
