摘要
The saccharide-based chiral bifunctional thiourea-phosphines were developed as chiral organocatalysts for the intramolecular Morita-Baylis-Hillman reaction of o^-formyl-enones. With only 2 tool% of thiourea-phosphine cata- lyst 3c, chiral functionalized cyclohexenes were achieved under mild reaction conditions with excellent yields and enantioselectivities.
