, p. 146 - 147 (2001)
α-Carbolines are synthesized from β-(3-indolyl) ketone O-2,4-dinitrophenyloximes by the treatment with sodium hydride and sodium cyanoborohydride.
A new route to α-carbolines based on 6π-electrocyclization of indole-3-alkenyl oximes

Indoles are converted into α-carbolines in four steps by acylation at C-3, Boc-protection, olefination of the resulting 3-indolyl aldehydes or ketones to give N-Boc-3-indolyl alkenyl oxime O-methyl ethers, which upon heating to 240 C under microwave irradiation undergo loss of the Boc-group, and 6π-electrocyclization to α-carbolines, following aromatization by loss of methanol (11 examples, 30-90% yield).
Thermal rearrangement of indolyl oxime esters to pyridoindoles

(Chemical Equation Presented) Acyl oximes derived from a variety of indolylalkanones underwent a ring closure sequence during FVP to afford 9H-pyrido[2,3-b]indoles. Unlike UV light promoted reactions of oxime esters, the mechanism is almost certainly not mediated by iminyl radicals but probably involves tautomerism, elimination of acetic acid, and a final electrocyclic ring closure.
Arylacetamides and their use as medicaments
-
, (2008/06/13)
The new arylacetamides are obtained by first converting appropriately substituted arylacetic acids into the acetyl chlorides and then converting these into the amides using the appropriate amines. The new arylacetamides can be used as active compounds in medicaments, in particular in antiatherosclerotic medicaments.
Amides and sulphonamides of benzylamines having heterocyclic substituents
-
, (2008/06/13)
Amides and sulphonamides of benzylamines having heterocyclic substituents are prepared by first converting the corresponding carboxylic acids into the corresponding amines and then substituting these on the amine nitrogen in a corresponding manner. The new amides and sulphonamides of benzylamines having heterocyclic substituents can be used as active compounds in medicaments, in particular in antiatherosclerotic medicaments.
Cycloalkano-indole and -azaindole derivatives
-
, (2008/06/13)
Cycloalkano-indole and -azaindole derivatives are prepared by reaction of appropriately substituted carboxylic acids with amines. The cycloalkano-indole and -azaindole derivatives are suitable as active compounds for medicaments, preferably antiatheroscle
