Formal [3 + 2] cycloaddition of azomethine ylides generated in situ with unactivated cyclic imines: A facile approach to tricyclic imidazolines derivatives

A simple and efficient method for the synthesis of tricyclic imidazolines derivatives via [3 + 2] 1,3-dipolar cycloaddition between nonstabilized azomethine ylide generated in situ with unactivated cyclic imines is reported here. The method provided easy and mild access to various fused tricyclic hexahydroimidazo[5,1-a]isoquinolines in excellent yields (up to 96%). This protocol is simple and easy to handle.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 3382-18-1, In my other articles, you can also check out more blogs about 3382-18-1

N-Acylazinium Salts: A New Source of Iminium Ions for Ugi-Type Processes

A multicomponent reaction involving the interaction of azines (quinolines, isoquinolines, and phenanthridine) with activating agents (chloroformates, acid halides, and sulfonyl halides), isocyanides, and water is described. The products of this process, alpha-carbamoylated-1,2-dihydroazines, are the result of the addition of the isocyanide partner to the N-acylazinium salt formed in situ. This represents a new source of iminium ion equivalents for Ugi-type reactions.

THE SYNTHESIS OF THE ISOQUINOLINE ALKALOID CALYCOTOMINE VIA FUNCTIONALIZATION OF ENAMIDE DOUBLE BONDS

The novel alkaloid calycotomine, a 1-hydroxymethylenetetrahydroisoquinoline, has been synthesized from 1-methyl-3,4-dihydroisoquinoline via the 2-benzyloxycarbonyl enamide derivative.Oxidation of the enamide with osmium tetroxide results in bis-hydroxylation and ring opening to form hydroxyacetophenone carbamates.Hydrogenation results in reclosure of the isoquinoline ring and further reduction yielding 1-hydroxymethylenetetrahydroisoquinolines.

Synthesis and biological evaluation of quinoline-imidazole hybrids as potent telomerase inhibitors: A promising class of antitumor agents

A series of 1-isoquinoline-2-styryl-5-nitroimidazole derivatives has been synthesized and screened for telomerase inhibitory as well as antiproliferative properties on four variant cancer cell lines (U251, Hela, HepG-2 and A549). The bioassay results showed that most of the designed compounds exhibited moderate to potent in vitro inhibitory activity in the enzymatic and cellular assays, of which compounds 3u and 3v were revealed the most potent telomerase inhibitors, with IC50 values of 0.98 muM and 1.92 muM, respectively, compared to staurosporine. Docking simulation was performed to position compounds 3u and 3v into the telomerase active site to determine the probable binding pose. Twenty three compounds were scrutinized by the CoMFA and CoMSIA techniques of 3D Quantitative Structure-Activity Relationship (QSAR). These new findings along with molecular docking observations could provide important information that compounds 3u and 3v with potent inhibitory activity in tumor growth inhibition may be potential anticancer agents.

X=Y-ZH SYSTEMS AS POTENTIAL 1,3-DIPOLES. PART 19. INTRAMOLECULAR CYCLOADDITIONS OF NON-STABILISED AZOMETHINE YLIDES GENERATED VIA THE DECARBOXYLATIVE ROUTE FROM alpha-AMINO ACIDS.

Heating a range of acyclic and cyclic secondary alpha-amino acids with aryl aldehydes containing a proximate terminal alkene or alkyne results in consecutive condensation and decarboxylation, followed by intramolecular cycloaddition of the resultant non-stabilised azomethine ylides.Evidence is produced for syn-anti dipole equilibration and it is found that intramolecular cycloadditions to a terminal alkyne involve only the anti-dipole and proceed via an exotransition state to give a single cycloadduct.In contrast, intramolecular cycloaddition to a terminal alkene involves both anti- and syn-dipoles, with trapping of the former being slightly energetically preferred, resulting in mixtures of two stereoisomeric cycloadducts.Intramolecular cycloadditions of terminal alkenes to anti-dipoles proceed via exo-transition states whilst analogous reactions of the syn-dipole involve endo-transition states.

A Class of Amide Ligands Enable Cu-Catalyzed Coupling of (Hetero)aryl Halides with Sulfinic Acid Salts under Mild Conditions

The amide derived from 4-hydroxy-l-proline and 2,6-dimethylaniline is a powerful ligand for Cu-catalyzed coupling of (hetero)aryl halides with sulfinic acid salts, allowing the formation of a wide range of (hetero)aryl sulfones from the corresponding (hetero)aryl halides at considerably low catalytic loadings. The coupling of (hetero)aryl iodides and sodium methanesulfinate proceeds at room temperature with only 0.5 mol % CuI and ligand, representing the first example for Cu-catalyzed arylation at both low catalytic loading and room temperature.

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 34784-05-9 is helpful to your research. 34784-05-9
