Tagging along: A system for phase‐switch synthesis has been developed. The boronicacid functionality is used as a phase tag that complexes to sorbitol and facilitates compound transfer from an organic solvent to water at high pH. The phase tag can then be used in a productivereaction step to generate targeted products, thereby eliminating purification by silica gel chromatography.
