Oxidative Ring-Opening of rel-(2R,3R,5S)-5-Aryl-2-benzoylamino-6,7-bis (methoxycarbonyl)-2,3-dihydro-1-oxo-3-phenyl-1H,5H-pyrazolo [1,2-a]-pyrazoles. Synthesis of rel-(2R,3R)-3-Phenyl-3- [5-aryl-3,4-bis(methoxycarbonyl)pyrazolyl-1]alanine Esters.
TL;DR: In this article, a cycloaddition of dimethyl acetylenedicarboxylate (3) to (1Z)-rel-(4R,5R)-1-aryl-methylidene-4-benzoylamino-5-phenyl-3-pyrazolidinone-1-azomethine imines is presented.
Journal ArticleDOI
A Simple Metal‐Free Synthesis of 2‐Substituted Pyridine‐4,5‐dicarboxylates and Their N‐Oxides.
TL;DR: In this article, a simple metal-free synthesis of 2-alkyl, 2-cycloalkyl-, 2-aryl-, and 2-heteroaryl-substituted pyridine 3,4-dicarboxylates and their N-oxides from the corresponding methyl ketones in good to excellent yield, demonstrated with 22 examples in each case, is described.
Journal ArticleDOI
Stereoselective Amination of 5-Substituted γ-Lactones and γ-Lactams. A Convenient Route for the Preparation of 5-Substituted (3S,5S)-3-Acetylaminotetrahydrofuran-2-ones and (3S,5S)-3-Acetylaminopyrrolidin-2-ones.
TL;DR: In this paper, 5-substituted (S)-tetrahydrofuran-2-ones (1a,b) and 3-acetylaminopyrrolidin-2 -ones (4c,d) were transformed in three steps, by treatment with tert-butoxybis(dimethylamino)methane (Bredereck's reagent), followed by nitrosation and stereoselective catalytic hydrogenation, into the corresponding (3S,5S)-3-actylamin
Journal ArticleDOI
Ring Contractions of 3-Azido-4H-quinolizin-4-ones and 3-Azido-4H-azino[1,2-x]pyrimidin-4-ones: A Novel Approach to 3-Aminoindolizines and Their Aza Analogues.
TL;DR: Thermal transformations of 3-azido-1-cyano-4H-quinolizin-4-ones 4a,b and 4c,d, available from the corresponding heteroarylamines 2a–d, were studied and the reaction products were mostly dependent on the solvent.
Journal ArticleDOI
Synthesis and Transformations of Ethyl 3-Formyl-1H-indole-2-carboxylate. Preparation of Aplysinopsin and β-Carboline Thiohydantoin Analogues.
TL;DR: In this article, various aplysinopsin and β-carboline thiohydantoin analogues were prepared starting from ethyl 3-formyl-1H-indole-2-carboxylate by condensation with the active methylene group of 2-THIHO derivatives.
