✦ Synopsis
Ring opening of indole functionalised methyleneaziridines (3a-c, 7) with alcohols in the presence of boron trifluoride etherate leads to the formation of 1,1-disubstituted tetrahydro-b-carbolines in moderate to good yields (37-83%).

The stereospecific synthesis of trans-1,3-disubstituted-1,2,3,4\_tetrahydro $-carbolines has been accomplished in good yield by a two step sequence which involves Pi&et-Spengler condensation of Nb-benzyltryptophan methyl: ester with aldehydes, followed by removal of the 2-benzyl moiety from the corr
## Abstract Reaction of tryptamine (1) with 2 and 3 gives the enamino ketones 4a and 5, resp., which on treatment with trifluoroacetic acid lead to the 2‐substituted indoles 8 and 9, respectively. Acylation of 4a followed by reaction with trifluoroacetic acid or a Lewis acid affords the 1,2,3,4‐tet
## Abstract Die Beziehungen zwischen Struktur und neuropsychotroper Wirkung bei 6 neuen 1,2,3,4‐Tetrahydro‐β‐carbolinen werden untersucht. Die aktivste Verbindung 4b hat ein pharmakologisches Profil, das dem Chlorpromazin ähnelt. Keine der Substanzen hat dopaminerge Eigenschaften.
