An efficient, two step synthesis of 3-(pyrrolidin-3-yl) indoles 4 is described. Indoles react with
maleimides in refluxing acetic acid affording 3-(indol-3-yl) succinimides 6. Reaction times …

The acetoxyindoles 10 and 11 are efficiently converted (85-95%) into the dihydro-1, 2-
oxazines 13 and 14, respectively, by reaction with the transient nitroso olefin 2, prepared in …

The stereoselective formation of 2-endo-substituted hexahydropyrrolo [2, 3-b] indoles from 2-
substituted tryptamine derivatives, especially tryptophan, is discussed. Parallels are drawn …

Of various methods available 1, the decarboxylation of tryptophan (1) is the simplest way to
the synthesis of tryptamine (3) which is a very important starting material in the synthesis of …

A series of new N-indol-3-ylmethylalkylamines (1) have been synthesized in excellent yields
via transamination between gramine and the appropriate primary alkylamine. The use of …

3, 3-Disubstituted N-(2-hydroxyethyl)-2-[1-(phenylsulfonyl)-3-indolyl]-piperidine 4 shows a
particular reactivity in front of KtBuO/BF3. Et2O: the intermediate spiroindolenine 15 evolves …

Attempts to isolate 3, 3-spiro-cyclicindolenines thought to be intermediates in the cyclization
of benzylidenetryptamines to tetrahydro-β-carbolines are described. One such spiro …
