WebAbstract: Ab initio quantum mechanical calculation reveals that the first Mannich reaction in Robinson’s tropinone synthesis involves both carbon–carbon bond formation and water … WebThe Robinson-Schopf condensation is a tandem process most notably recognized as the reaction between one molecule of succinaldehyde (1), methyl amine (2), and acetone dicarboxylic acid 3 to give the bicyclic product tropinone (4) in a one-pot procedure.

Robinson-Schöpf reaction

The first synthesis of tropinone was by Richard Willstätter in 1901. It started from the seemingly related cycloheptanone, but required many steps to introduce the nitrogen bridge; the overall yield for the synthesis path is only 0.75%. Willstätter had previously synthesized cocaine from tropinone, in what was the first synthesis and elucidation of the structure of cocaine.
