The saccharide-based chiral bifunctional thiourea-phosphines were developed as chiral organocatalysts for the intramolecular Morita-Baylis-Hillman reaction of ω-formyl-enones. With only 2 mol% of thiourea-phosphine catalyst 3c, chiral functionalized cyclo

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 ω-for

This work demonstrates that, in accord with metal catalysis, ferrocene could be an excellent scaffold for organocatalysts. The simple and easily accessible bifunctional ferrocene-based squaramide-phosphine shows high enantioselectivity in the intramolecul
Chiral phosphine-squaramides as enantioselective catalysts for the intramolecular Morita-Baylis-Hillman reaction

supporting information; experimental part, p. 1012 - 1014 (2011/02/26)
Novel squaramides containing tertiary phosphine were developed as chiral bifunctional organic catalysts to promote the asymmetric intramolecular Morita-Baylis-Hillman reaction of ω-formyl-enones. The adducts were obtained in high yields with good-to-excel
The enantioselective intramolecular Morita-Baylis-Hillman reaction catalyzed by amino acid-derived phosphinothiourea

A series of chiral bifunctional phosphinothioureas derived from l-amino acids have been developed to promote the enantioselective intramolecular Morita-Baylis-Hillman reaction. The process afforded the cyclic hydroxyl enones with up to 84% ee and good yields under mild conditions.
Enantioselective intramolecular Morita-Baylis-Hillman reaction using chiral bifunctional phosphinothiourea as an organocatalyst
Yuan, Kui,Song, Hong-Liang,Hu, Yinjun,Fang, Jian-Fei,Wu, Xin-Yan
experimental part, p. 903 - 908 (2010/08/06)
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
