ESTUDOS VISANDO A SÍNTESE DE DIAMINAS DERIVADAS DE PINENOS COM POTENCIAIS ATIVIDADES NOS RECEPTORES NICOTÍNICOS DO SISTEMA NERVOSO CENTRAL
… work are described the attempts of generating stereoselective syntheses of the 1,2,3-triazolic and piridine amines Ia,b-IVa,b, which constitutes in new analogous of the nicotine with potential activities as agonists of the nicotinic receptors. All the substances aimed are nicotinic analogous …

Synthesis of Analogues Based on the Opioid Alkaloid Mitragynine
… Unfortunately, this work did not focus on stereoselective syntheses or chiral separations, which in the case of the chiral tetrahydro-beta-carbolines could have given valuable insights about the spatial requirements for affinity among the three main opioid receptors.

Untersuchungen zur stereoselektiven Synthese funktionalisierter Tetrahydrofurane durch Vanadium(V)- und Cobalt(II)-katalysierte Oxidationen substituierter Bishomoallylalkohole
Substituierte Tetrahydrofurane sind Bausteine vieler pharmakologisch interessanter Natur- und Wirkstoffe. Deshalb ist die Entwicklung effizienter Methoden zur Darstellung dieser Verbindungsklasse von großer Bedeutung. Bei den Übergansmetall-katalysierten Verfahren erwiesen sich sowohl Vanadium(V)-, …
