  Chiral cyclohexane-based phosphinothioureas were found to be efficient organocatalysts for the enantioselective intramolecular Morita–Baylis–Hillman reaction of ω-formyl-enone. Among the solvents screened, t-BuOH was the best one which provided good yield and enantioselectivity. Moreover in the presence of 3 mol % of phosphinothiourea 2b, the desired products were obtained in good-to-excellent yields

  Novel chiral bifunctional thiourea derivatives have been synthesised and successfully applied to the intermolecular Morita-Baylis-Hillman (MBH) reaction of an aromatic aldehyde with methyl vinyl ketone (MVK) and to the intramolecular MBH reaction of omega-formyl-enone. The corresponding products were obtained with high enantioselectivities (up to 98 % ee). The thiourea organocatalyst derived from a B-amino alcohol gave high enantioselectivities (92 % ee) in the intermolecular MBH reaction, whereas the same chiral ligand afforded the corresponding product in high yield (85 %) with moderate enantioselectivity (75 % ee) in the intramolecular MBH reaction. The use of a thiophene ring-containing thiourea derivative gave high enantioselectivities in the intermolecular and intramolecular MBH reactions (85 % and 95 % ee, respectively).[GRAPHICS].
