Chiral Urea/Thiourea

Chiral urea/thiourea compounds play an important role in asymmetric catalytic reactions as catalyst ligands or catalysts themselves. They can significantly improve the selectivity and efficiency of catalytic reactions through hydrogen bond donor effects, metal coordination, and stereo control. Whether in metal-catalyzed reactions or reactions that do not rely on metal catalysis, chiral urea/thiourea can provide strong support for efficient organic synthesis.
