Common Strategy for the Synthesis of Some Strychnos Indole Alkaloids

Indole alkaloids are important natural compounds with interesting bio-activities that can be found in various species belonging to the Amaryllidaceae, Apocynaceae, or Strychnaceae families. Although these compounds have different connections, substituents, and functionalities, their main core can be produced via the formation of a common functionalized tetracyclic subunit, which is rapidly obtained by an oxidative de-aromatization process mediated by a hypervalent iodine reagent from an inexpensive phenol containing a lactate moiety as the chiral auxiliary. A subsequent stereoselective aza-Michael addition and an intramolecular Heck-type reaction lead to the formation of a common key intermediate. This approach provides a solid foundation for the further elaborations of several natural products. The asymmetric syntheses of (-)-strychnopivotine and the polycyclic main cores of (-)-strychnosplendine, (+)-isosplendine, and (+)-malagashanol, three other indole alkaloids, are reported.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 114615-82-6 is helpful to your research., Application of 114615-82-6

A double donor-activated Ruthenium(VII) catalyst: Synthesis of enantiomerically pure THF-Diols

“Chemical Equation Presented” Double, double, no toll and trouble: Enantiomerically pure tetrahydrofurans are obtained with high position- and stereoselectivity through a ruthenium(Vll)-catalyzed oxidative cyclization of 5,6dihydroxy alkenes (see scheme TPAP = tetrapropylammonium perruthenate). A dual activation modifies the reactivity and increases the carbophilicity of the transition metal so that an otherwise unusual dioxygenation with perruthenate occurs.

Piperidine and tetrahydropyridine derivatives

A class of substituted piperidine and tetrahydropyridine derivatives, linked through the 4-position thereof via an alkylene chain to a fused bicyclic heteroaromatic moiety such as indolyl, and further substituted at the 1-position by an optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl-alkyl, aryl-alkyl or heteroaryl-alkyl moiety, are selective agonists of 5-HT1 -like receptors, being potent agonists of the human 5-HT1Dalpha; receptor subtype whilst processing at least a 10-fold selective affinity for the 5-HT1Dalpha; receptor subtype relative to the 5-HT1Dbeta; subtype; they are therefore useful in the treatment and/or prevention of clinical conditions, in particular migraine and associated disorders, for which a subtype-selective agonist of 5-HT1D receptors is indicated, whilst eliciting fewer side-effects, notably adverse cardiovascular events, than those associated with non-subtype-selective 5-HT1D receptor agonists.

Synthesis and CYP24A1-Dependent Metabolism of 23-Fluorinated Vitamin D3 Analogues

Two novel 23-fluorinated 25-hydroxyvitamin D3 analogues were synthesized using Inhoffen-Lythgoe diol as a precursor of the CD-ring, efficiently. Introduction of the C23 fluoro group was achieved by the deoxy-fluorination reaction using N,N-diethylaminosulfur trifluoride or 2-pyridinesulfonyl fluoride (PyFluor). Kinetic studies on the CYP24A1-dependent metabolism of these two analogues revealed that (23S)-23-fluoro-25-hydroxyvitamin D3 was more resistant to CYP24A1-dependent metabolism than its 23R isomer.

Total Synthesis of Naturally Occurring 5,7,8-Trioxygenated Homoisoflavonoids

Homoisoflavonoids are in the subclass of the larger family of flavonoids but have one more alkyl carbon than flavonoids. Among them, 5,7,8-trioxygenated homoisoflavonoids have not been extensively studied for synthesis and biological evaluation. Our current objective is to synthesize 2 5,7,8-trioxygenated chroman-4-ones and 12 5,7,8-trioxygenated homoisoflavonoids that have been isolated from the plants Bellevalia eigii, Drimiopsis maculata, Ledebouria graminifolia, Eucomis autumnalis, Eucomis punctata, Eucomis pallidiflora, Chionodoxa luciliae, Muscari comosum, and Dracaena cochinchinensis. For this purpose, 1,3,4,5-tetramethoxybenzene and 4?-benzyloxy-2?,3?-dimethoxy-6?-hydroxyacetophenone were used as starting materials. Asymmetric transfer hydrogenation using Noyori’s Ru catalyst provided 5,7,8-trioxygenated-3-benzylchroman-4-ones with R-configuration in high yield and enantiomeric excess. By selective deprotection of homoisoflavonoids using BCl3, the total synthesis of natural products including 10 first syntheses and three asymmetric syntheses has been completed, and three isomers of the reported dracaeconolide B could be provided. Our research on 5,7,8-trioxygenated homoisoflavonoids would be useful for the synthesis of related natural products and pharmacological applications.
