The quest for quinine: those who won the battles and those who won the war.
TL;DR: The recently disclosed syntheses of quinine testify in a remarkable manner the huge progress made by organic synthesis during the last three decades since the first series of partially controlled syntheses by the group of Uskokovic.

Sebastião Ferreira Fonseca,Jayr de Paiva Campello,Lauro Euclides Soares Barata,Edmundo A. Rúveda +3 more
TL;DR: In this article, the structure of the monomethyl ether of isolariciresinol has been established based on the 13 C NMR spectra of these compounds, their methyl and acetyl derivatives, and the corresponding one of matairesinols.
Journal ArticleDOI

Antonio Claudio Herrera Braga,Susana A. Zacchino,Hector Badano,Manuel Gonzalez Sierra,Edmundo A. Rúveda +4 more
TL;DR: In this article, the 13C NMR spectra of the erythro and threo forms of representative members of the 8-O-4′ type of neolignans were recorded and the signals assigned.
Journal ArticleDOI
Neolignans of Virola surinamensis
TL;DR: Elemicin, galbacin, veraguensin and two new neolignans, surinamens in and virolin, were isolated and characterized from the leaves of VirolaSurinamensis.
Journal ArticleDOI
Lignans of Araucaria angustifolia and 13C NMR analysis of some phenyltetralin lignans
TL;DR: In this paper, the position of the OH group was located in these compounds and the 13 C NMR spectra of the phenyltetralin lignans galbulin, galcatin, isogalcatin and cyclogalgravin were also recorded.
