Phosphine–Thiourea‐Organocatalyzed Asymmetric C−N and C−S Bond Formation Reactions

Phosphine–thiourea based-organocatalysts derived from l-proline promoted C−N or C−S bond formation of tert-butoxycarbonyloxy-Morita—Baylis—Hillman adducts with phthalimide or alkyl thiols, respectively. Good yields and enantioselectivities up to 93 % were achieved.
