Exploring an alternative approach to the synthesis of arylalkyl and indolylmethyl glucosinolates
摘要:
A new approach to the elaboration of hydroximoyl chlorides - key-compounds in the synthesis of glucosinolates - based on nitrovinyl intermediates was explored in the case of arylalkyl conjugates and their indolylmethyl counterparts. (C) 1998 Elsevier Science Ltd. All rights reserved.
The first total synthesis of racemic topsentin C, a secondary metabolite from Hexadella sp., based on this approach is reported. The initially proposed structure for topsentin C has been revised. An efficient syntheticapproach to access (indol-3-yl)ethane-1,2-diamines with a protecting group at the indole N atom from readily available 3-(2-nitrovinyl)indoles is reported. This approach includes solvent-free
Selectivity of Sterically Fixed Tryptamine and 5-Methoxytryptamine Derivatives for Serotonin Receptor Subtypes, I: Synthesis ofN-Alkyl- andN,N-Dialkyl-3-indolylbicyclo[2.2.1]heptane-2-amines

Twenty‐six title compounds with the ethylamine part of tryptamine or 5‐methoxytryptamine fixed in an anticlinal ecliptic conformation were synthesized for assaying them at the different known serotoninreceptors. Several alkylation methods have been improved and adapted for the space consuming norbornane system. The structures were fully elucidated by high‐field NMR spectroscopy. All 1H‐ and 13C‐signals

1]heptan‐2‐amine und sechs 3‐Indolyl‐1,4:5,8‐perhydrodimethanonaphthalin‐2‐amine, in denen die ekliptische Konformation von Tryptamin‐, 5‐Methoxytryptamin‐ und 5‐Hydroxytryptaminstrukturen sterisch fixiert ist, wurden dargestellt. Die Tryptaminanaloga 12a–14a zeigen hohe und spezifische Affinität zu neuronalen 5‐HT‐2‐Rezeptoren während die Serotoinananaloga 16–19 hochgradige (IC50 < 1 μmol/l) und spezifische
