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%. [5] Willstätter had previously synthesized cocaine from tropinone, in what was the first synthesis and elucidation of the structure of cocaine. [6] Willstatter tropinone ...
Chemical structure of cocaine. The biosynthesis of cocaine has long attracted the attention of biochemists and organic chemists. This interest is partly motivated by the strong physiological effects of cocaine, but a further incentive was the unusual bicyclic structure of the molecule. The biosynthesis can be viewed as occurring in two phases ...
2-Carbomethoxytropinone (2-CMT) is a commonly used organic intermediate in the synthesis of cocaine and its analogues. [1] As of at least 1999 no reaction pathway has been discovered that synthesizes cocaine-like compounds without utilizing the reduction of 2-CMT. [2]
By the 17th century, when those buried in the crypt would have lived, Milan (then a possession of Spain) was a major importer of exotic plants, especially from the Americas, so cocaine could’ve ...

The term may also be loosely used to refer to drugs manufactured from cocaine or having their basis as a total synthesis of cocaine, but modified to alter their effect & QSAR. These include both intracellular sodium channel blocker anaesthetics and stimulant dopamine reuptake inhibitor ligands (such as certain, namely tropane-bridged-excised ...
A similar, more recent synthesis pathway involves producing 2-tropinone from cocaine and treating the product with ethyl chloroformate producing a bicyclic ketone. This product is combined with trimethylsilyldiazylmethane, an organoaluminum Lewis acid and trimethylsinyl enol ether to produce tropinone.
The additional carbon atoms required for the synthesis of cocaine are derived from acetyl-CoA, by addition of two acetyl-CoA units to the N-methyl-Δ 1-pyrrolinium cation. [142] The first addition is a Mannich-like reaction with the enolate anion from acetyl-CoA acting as a nucleophile toward the pyrrolinium cation. The second addition occurs ...
