Tropinone is a bicyclic molecule, but the reactants used in its preparation are fairly simple: succinaldehyde, methylamine and acetonedicarboxylic acid (or even acetone ).

WebA recent stereoselective synthesis of coccinelline (4), an alkaloid used by the ladybug for defense, has been achieved by use of a variant of the classical Robinson-Schopf synthesis of tropinone. The reaction of 1 with acetonedicarboxylic ester at pH 5.5 yields a single product in 75 % yield, even though five chiral centers are produced.
