The regioselective synthesis of carbamates from bio‐derived cyclic carbonates and amines by using 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) as an organocatalyst is reported. This methodology led to the preparation of a wide range of bio‐sourced hydroxyurethanes from furan‐, carvone‐ and limonene‐based scaffolds under solvent‐free and mild reaction conditions. Moreover, a comprehensive analysis of the process allowed us to optimize the catalyst loading with little or no impact on the process regioselectivity.
