History of amphetamine and methamphetamine

Amphetamine was first synthesized in 1887 in Germany by Romanian chemist, Lazăr Edeleanu, who named the drug phenylisopropylamine.[4][3][17][2] This concoction was one of a series of compounds related to the plant derivative ephedrine, which had been isolated from the plant má huáng (ephedra) that same year by Nagayoshi Nagai.[6] Shortly after the first synthesis of amphetamine, Nagai synthesized methamphetamine from ephedrine in 1893.[7][18]…

Tropinone synthesis via an atypical polyketide synthase

Tropinone is the first intermediate in the biosynthesis of the pharmacologically important tropane alkaloids that possesses the 8-azabicyclo[3.2.1]octane core bicyclic structure that defines this alkaloid class. Chemical synthesis of tropinone was achieved in 1901 but the mechanism of tropinone biosynthesis has remained elusive. In this study, we identify a root-expressed type III polyketide synthase from Atropa belladonna…

ISOPROPYLBENZYLAMINE

2-Carbomethoxytropinone (2-CMT) is a commonly used organic intermediate in the synthesis of cocaine and its analogues. As of at least 1999 no reaction pathway has been discovered that synthesizes cocaine-like compounds without utilizing the reduction of 2-CMT. The structure of cocaine was discovered by Richard Willst?tter in 1898 after he synthesized it from 2-carbomethoxytropinone. Although it was originally believed that 2-CMT in nature was ultimately derived…
