phosphorus-free catalyst for the Morita–Baylis–Hillmanreaction is disclosed. A bicyclicimidazolylalcohol having a Lewis basic center associated with a hydrogen-bond donor group was used as catalyst for the reaction. Aliphatic cycloalkanones such as 2-cyclopentenone and 2-cyclohexanone and aliphatic and aromatic aldehydes were used successfully, and the reaction was found to work nicely using water
