The development of a highlyactive solid‐phase catechol–copper network catalyst for directaldolreaction is described. The catalyst was prepared from an alkyl‐chain‐linked bis(catechol) and a copper(II) complex. The directaldolreaction between carbonyl compounds (aldehydes and ketones) and methyl isocyanoacetate was carried out using 0.1–1 mol % [Cu] catalyst to give the corresponding oxazolines
