Tropinone synthesis
- Product Name:Tropinone

- Molecular formula:C8H13NO
- Molecular Weight:139.2
The 1917 synthesis by Robinson is considered a legend in total synthesis due to its simplicity and biomimetic approach. Tropinone is a bicyclic molecule, but the reactants used in its preparation are fairly simple: succinaldehyde, methyl amine and acetone dicarboxylic acid (or even acetone). The synthesis is a good example of a biomimetic reaction or biogenetic-type synthesis because biosynthesis makes use of the same building blocks. It also demonstrates a tandem reaction in a one-pot synthesis. Furthermore the yield of the synthesis was 17% and with subsequent improvements exceeded 90%.

with sodium tetrafluoroborate;potassium hydroxide in acetone at 100; for 12 h;Inert atmosphere;Schlenk technique;Oppenauer Oxidation;
Steps:
3.8. General procedure for catalytic Oppenauer-type oxidation
General procedure: To a mixture of ruthenium complex (0.04 mmol), KOH (0.4 mmol) and NaBF 4 (0.16 mmol) were added acetone (2 mL) and a substrate (0.8 mmol), the resulting mixture was heated at reflux in argon for 12 h or 100 °C for 12 h with some inactive substrates ( Table 3 , 2o-2r ). After the reaction completed, the prod- uct was isolated by column chromatography on silica gel with dichloromethane-petroleum ether as eluents.
