Abstract A series of camphor-derived thiourea organocatalysts 3a–f were designed and synthesized from (1 R ,3 S )-camphoric acid 1 and applied to the one-potthree-component Kabachnik–Fields reaction. Catalyst 3c was found to be an efficientorganocatalyst for the reaction of 2-cyclopropylpyrimidin-4-carbaldehyde 4 , various amines 5, and diphenylphosphite 6 to yield the corresponding enantioselective
