A novel and advantageous protocol for accessing carbamates through the known three-component coupling reaction involving carbondioxide, amines, and alkyl halides is described. Employing mild conditions, simple experimental set-up, and immobilized DBU, this protocol addresses several drawbacks from the previous described methods. No classical purification procedures are necessary and the immobilized

N‐alkyl aminomalonates undergo a fast and selective intramolecular C→N acylrearrangement reaction in the presence of a strong base, leading to N‐protected glycinates in excellent yield. Moreover, the fact that the reaction proceeds through a nucleophilic enolate intermediate has been used for implementing a tandem rearrangement/alkylation sequence that has been applied to the preparation of synthetically
