Polycondensed Heterocycles. Part 11: Preparation and Regioselective Reductions of 5-Phenyl-4H-pyrrolo[1,2-a][1]benzazepin-4-one
摘要:
The Wadsworth-Emmons olefination between 2-(1H-pyrrol-1-yl)benzaldehyde and methyl alpha-(diethylphosphonyl)phenyl acetate leads exclusively to the cis-isomer of methyl 2-(1H-pyrrol-1-yl)-alpha -phenylcinnamate, which, after transformation into the corresponding acid chloride, was easily cyclised to the title enone. This latter was regioselectively reduced to the corresponding saturated ketone or unsaturated alcohol, under different experimental conditions. An improved preparation of starting 2-(1H-pyrrol-1-yl)benzaldehyde is also reported. (C) 2000 Elsevier Science Ltd. All rights reserved.
Specific Targeting Highly Conserved Residues in the HIV-1 Reverse Transcriptase Primer Grip Region. Design, Synthesis, and Biological Evaluation of Novel, Potent, and Broad Spectrum NNRTIs with Antiviral Activity
human immunodeficiency virus type 1 (HIV-1) nonnucleoside reverse transcriptase (RT) inhibitors (NNRTIs) whose prototype is 5. Molecular modeling studies based on the X-ray structures of HIV-1 RT prompted the synthesis of novel analogues which were tested as anti-HIV agents. The PBO derivatives specifically designed to target the highlyconserved amino acid residues within the beta12-beta13 hairpin, namely

synthesized and tested novel pyridopyrrolo- and pyrrolobenzoxazepine derivatives, as novel and selective peripheral type benzodiazepine receptor (PBR) ligands, and their ability to modulate steroid biosynthesis has been investigated. A subset of new ligands bind the PBR (rat brain and testis) with picomolar affinity, representing the most potent ligands that have been identified to date, and elicited effects
