Key Word Index - Virola sebifera; Myristicaceae; hallucinogenic plant; alkaloids; N-methyl-N-acetyltryptamine; N-methyl-N-formyltryptamine; 2-methyl-1,2,3,4-tetrahydro-β-carboline; N,N-dimethyltryptamine; N,N-dimethyltryptamine-N-oxide; N-monomethyltryptamine. - Bark of Virola sebifera used in the preparation of hallucinogenic snuffs and drinks in Venezuela has yielded N-methyl-N-formyltryptamine and N-methyl-N-acetyltryptamine, which exist in two rotameric forms reflecting hindered rotation around the carbon-nitrogen bond of the amide function.They were detected by HPLC as well as NMR. 2-Methyl-1,2,3,4-tetrahydro-β-carboline, N,N-dimethyltryptamine, its oxide and N-monomethyltryptamine were also identified.
Successful bridging from a peptide to a non peptide antagonist at the human tachykinin NK-2 receptor

Non peptide products have been found to show nanomolar binding and functional affinities at the human tachykinin NK-2 receptor. The new antagonists do not possess stereogenic centers and their thermal behaviour in solution is featured by a peculiar set of conformational stereoisomers. A macroscopic viewpoint is preferentially adopted to rationalize the obtained results.
Ruthenium Pincer Complex Catalyzed Selective Synthesis of C-3 Alkylated Indoles and Bisindolylmethanes Directly from Indoles and Alcohols

Herein, we presented Ru-SNS complex that serves as a useful catalyst for C-3 alkylation of 1H-indoles with various aliphatic primary and secondary alcohols including cyclic alcohols as well as benzylic alcohols. The selective synthesis of bisindolylmethane derivatives is also achieved from the same set of indole and alcohol just by altering the reaction parameters. Furthermore, the sustainable synthesis of C-3 alkylated indoles directly from 2-(2-nitrophenyl)ethan-1-ol and alcohols catalysed by a Ru-complex via “borrowing hydrogen” strategy is reported. This protocol provides an atom-economical sustainable route to access structurally important compounds like arundine, vibrindole A and tryptamine based derivatives. (Figure presented.).

Well-Defined Phosphine-Free Iron-Catalyzed N-Ethylation and N-Methylation of Amines with Ethanol and Methanol
Lator, Alexis,Gaillard, Sylvain,Poater, Albert,Renaud, Jean-Luc
supporting information, p. 5985 - 5990 (2018/10/02)
An iron(0) complex bearing a cyclopentadienone ligand catalyzed N-methylation and N-ethylation of aryl and aliphatic amines with methanol or ethanol in mild and basic conditions through a hydrogen autotransfer borrowing process is reported. A broad range of aromatic and aliphatic amines underwent mono- or dimethylation in high yields. DFT calculations suggest molecular hydrogen acts not only as a reducing agent but also as an additive to displace thermodynamic equilibria.
