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 ...
The structure of cocaine was discovered by Richard Willstätter in 1898 after he synthesized it from 2-carbomethoxytropinone. [ 3 ] [ 4 ] Although it was originally believed that 2-CMT in nature was ultimately derived from ornithine and acetic acid , [ 5 ] subsequent research has indicated other pathways exist for the biosynthesis of 2-CMT.

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 ...
Although cocaine use became widespread in the 19th century once it was synthesized into cocaine hydrochloride salts, Europeans knew of the coca plant’s stimulating effects since the early 15th ...
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 ...
Now that we’re a few episodes into MGM+’s Hotel Cocaine, it’s time to answer the question: How do the members of the 1970s drama fake-snort all that prop powder?. Answer, according to Mark ...
