TLDR
The Cinchonamin this article is a base C19H24ON2, which is an einsaurige Base C19h24on2, welche im UV ist ein fur Indol-Derivate charakteristisches Absorptionsspektrum.Abstract:
1. Das Cinchonamin ist eine einsaurige Base C19H24ON2, welche im UV. ein fur Indol-Derivate charakteristisches Absorptionsspektrum aufweist und zusatzlich zum Indol-Ring eine leicht hydrierbare Doppelbindung besitzt. Der Sauerstoff ist in Form einer Hydroxyl-Gruppe anwesend.read more

The hydrogenolysis of 3-hydroxymethylindole and other indole derivatives with lithium aluminum hydride
Edward Leete,Léo Marion +1 more
TL;DR: In this article, the expected reduction product, 3-hydroxymethylindole, was obtained by the action of sodium hydroxide on gramine methiodide, and its alkyl ethers were readily reduced to skatole.

Organometallic reagents in synthesis : A new protocol for construction of the indole nucleus
TL;DR: In this article, a large-scale procedure for preparation of monosilylated anilines was also developed, and efficient syntheses of ( + )-cinchonamine and (+ )-epi-catchonamine as well as a tetracyclic model system for the architecturally complex penitrem mycotoxins were completed in regio-and stereoselective fashion.

Biogenesis of the strychnos alkaloids.
TL;DR: ROBINSON 1 and Schöpf2 have developed the concept that a fundamental reaction of biogenesis involves the condensation between an amino group, a carbonyl group and an anionoid centre.

Structure and Biogenesis of Emetine
TL;DR: The remarkable development mentioned below certainly meets this requirement and provides an outstanding example of interaction of results in two fields, strengthening theoretical conclusions in both of them.
