1-(2′-Bromobenzyl)-6,7-dihydroxy- N-methyl-tetrahydroisoquinoline and 1,2-Demethyl-nuciferine as Agonists in Human D2 Dopamine Receptors

Certain D2-like dopamine receptor (DR) agonists are useful therapeutically as antiparkinsonian drugs, whereas D2-like DR antagonists or partial agonists are proven effective as antipsychotics. Two isoquinoline derivatives, 1-(2′-brom

PALLADIUM CATALYZED INSERTION OF CARBON MONOXIDE INTO BENZYL-TETRAHYDROISOQUINOLINES. A NEW SYNTHESIS OF BERBINE ALKALOIDS

A new total synthesis of the berbine alkaloid ring system has been achieved.Palladium catalyzed insertion of carbon monoxide into the 1-(2-bromobenzyl)-substituted-1,2,3,4-tetrahydroisoquinolines (1a-d) by the use of catalytic amounts of palladium diaceta

Synthesis and evaluation of nuciferine and roemerine enantiomers as 5-HT2 and α1 receptor antagonists

In this study, the (S)-enantiomers of the aporphine alkaloids, nuciferine and roemerine, were prepared via a synthetic route involving catalytic asymmetric hydrogenation and both stereoisomers were evaluated in vitro for functional activity at human 5-HT2 and adrenergic α1 receptor subtypes using a transforming growth factor-α shedding assay. Both enantiomers of each of the compounds were found to act as antagonists at 5-HT2 and α1 receptors. (R)-roemerine was the most potent compound at 5-HT2A and 5-HT2C receptors (pKb = 7.8-7.9) with good selectivity compared to (S)-roemerine at these two receptors and compared to its activity at 5-HT2B, α1A, α1B and α1D receptors.

Aporphine alkaloid synthesis and diversification via direct arylation

Palladium-catalyzed direct arylation of aryl chlorides, bromides and iodides has been applied to the preparation of new aporphine analogues including C2-substituted aporphines by reaction with benzodioxole, pyridine N-oxide and pyrazine N-oxide. Successful application of direct arylation in these diversification reactions highlights its utility not only in convergent, but also in divergent synthesis. We also describe enantioselective syntheses of (R)-nornuciferine and (R)-nuciferine employing a catalytic asymmetric transfer hydrogenation in high yield and excellent enantiomeric excess.

A variation of the Pictet-Spengler reaction via a sequential reduction-cyclization reaction of N-acylcarbamates: synthesis of 1-substituted tetrahydroisoquinoline derivatives

A new variation of the Pictet-Spengler reaction for the synthesis of 1-substituted tetrahydroisoquinoline derivatives has been developed. The reaction employs the reduction of N-acylcarbamates by DIBAL-H followed by simultaneous cyclization mediated by BF3·OEt2. The synthetic potential of this method has been illustrated by the synthesis of the tetrahydroisoquinoline alkaloids, (±)-xylopinine, (±)-laudanosine, (±)-8-oxo-O-methylbharatamine, and (±)-isoindoloisoquinolone.
