N-Heterocycle construction via cyclic sulfamidates. Applications in synthesis

When combined with an appropriate nucleophilic component, 1,2- and 1,3-cyclic sulfamidates function as versatile precursors to a range of substituted and enantiopure heterocyclic classes. Functionalised enolates provide a direct entry to C-3 functionalised lactams, as exemplified by total syntheses of (-)-aphanorphine, (+)-laccarin and (-)-paroxetine. Heteroatom nucleophiles, such as thiol esters, amino esters and bromo phenols, provide concise access to a range of enantiomerically pure thiomorpholine, piperazine and benzofused heterocyclic scaffolds. The latter methodology enables a facile synthesis of the antibacteriocidal agent levofloxacin.

Identification of Advanced Reaction Products Originating from the Initial 4-Oxo-2-nonenal-cysteine Michael Adducts

4-Oxo-2-nonenal (ONE), an aldehyde originating from the peroxidation of omega 6 polyunsaturated fatty acids, preferentially reacts with the cysteine residues of protein. Despite the fact that there has been significant recent interest in the protein reactivity and biological activity of ONE, the structural basis of the ONE-cysteine adducts remain to be established. In the present study, to gain a structural insight into the sulfhydryl modification by ONE, we characterized reaction products that originated from the initial ONE-cysteine Michael adducts. N-Acetyl-L-cysteine (10 mM) was incubated with an equimolar concentration of ONE in 0.1 M phosphate buffer (pH 7.4) at 37 degrees C. Within I h of incubation, the reaction of N-acetyl-L-Cysteine with ONE resulted in the formation of two (C-2 and C-3) Michael addition products possessing a carbonyl functionality. Subsequent incubation of the reaction mixture resulted in their disappearance and concomitant formation of advanced reaction products, including a minor product III and major products IVa, IVb, and V. Product III was identified to be a thiomorpholine derivative, 4-acetyl-5-hydroxyl-6-(2-oxoheptyl)thiomorpholine-3-carboxylic acid, which might have originated from the C-2 Michael addition product. The major products were identified to be the novel 2-cyclopentenone derivatives, that is, 2-(acetylamino)-3-[(3-butyl-4-oxocyclopent-2-en-1-yl)sulfanyl] propionic acid (IVa and its isomer IVb) and 2-(acetylamino)-3-[(4-butyl-5-oxocyclopent-3-en-1-yl)sulfanyl]propionic acid (V), which might be generated through the base-catalyzed cyclization of the C-2 and C-3 Michael addition products, respectively. The furan derivative, which has been reported as the end product of the Michael adducts, was found to be formed only under acidic conditions. Thus, this study identified the novel ONE-cysteine adducts, including the most prominent 2-cyclopentenone derivatives, that originated from the initial Michael adducts.

1D and 2D Silver-Based Coordination Polymers with Thiomorpholine-4-carbonitrile and Aromatic Polyoxoacids as Coligands: Structure, Photocatalysis, Photoluminescence, and TD-DFT Study

Four silver-based coordination polymers, {[Ag(L)(2)](BF4)}(infinity) (1), {[Ag(H2BTC)(L)]center dot(H3BTC)}(infinity) (2), {[Ag-2(H2BTEC)(L)(2)]..3.33H(2)O}(infinity) (3), and [Ag(H(25)SSA)(L)](infinity) (4), were synthesized using thiomorpholine-4-carbonitrile (L) as the primary ligand and three aromatic polyoxoacids as coligands: trimesic (H3BTC), pyromellitic (H4BTEC), and 5-sulfosalicylic acid (H(35)SSA). Compounds 1 and 3 are two-dimensional, while 2 and 4 are one-dimensional. L acts as a bis-monodentate ligand, while the Ag(I) ion is three-coordinated in 2 and four-coordinated in all of the other compounds. The tetrahedral coordination of Ag(I) in 3 leads to an almost complete absence of intermolecular interactions with the metal center. All compounds show reasonable photocatalytic activity for photocatalytic degradation of mordant blue 9 dye, with reaction rates in the 0.036-0.056 min(-1) range. Changes in the reaction rates can be correlated with the type and coordination of the coligand. Complex 3 exhibits photoluminescence at 77 K, while 4 exhibits photoluminescence at both room temperature and 77 K. Luminescence lifetimes indicate electronic transitions of singlet parentage, where transitions are allowed. A TD-DFT study determined the contributions of individual singlet-singlet electronic excitations to the fluorescence, indicating that metal- intraligand transitions are responsible for luminescence in both complexes.

Framework deformation of the microporous vanadium benzenedicarboxylate MIL-47 upon absorption of organosulfur molecules

Deformation of the microporous MIL-47 framework VO(bdc), bdc = 1,4-benzenedicarboxylate, upon absorption of carbon disulfide, tetrahydrothiophene, thiomorpholine and thioxane is investigated by single crystal X-ray diffraction. Intercalation of CS2 significantly expands the channel opening by a breathing deformation mode of the framework characterized solely by a cooperative translation of the octahedral chains, in contrast to intercalation of many other molecules that usually cause contraction of the channel opening. Upon loading of CS2 the short diagonal of the rhombic channel expanded by 0.91 angstrom and the maximum spherical void diameter increases to 8.0 angstrom from 7.6 angstrom of VO(bdc) with empty channels. Loading of the three cyclic organosulfur molecules all results in a strong twisting deformation of the framework featured by cooperative rotation of the octahedral chains by 21.3 degrees-28.2 degrees, bending of the bdc ligand and lowering of the space group symmetry from Pnma to P2(1)2(1)2(1). The maximum spherical void diameter of the framework decreases to 6.8 angstrom from 7.6 angstrom upon intercalation of tetrahydrothiophene or thiomorpholine, and to 6.0 angstrom upon intercalation of thioxane. Intercalation of thioxane leads to the highest degree of twisting known for the VO(bdc) framework combined with a substantial breathing contraction of the channel. The host-guest interactions are predominantly van der Waals in nature and the framework deformations are presumably driven by maximizing the van der Waals contacts. (C) 2015 Elsevier Inc.

Complexation of Constrained Ligands Piperazine, N-substituted Piperazines, and Thiomorpholine

Complexation of the symmetric cyclic diamine piperazine (1,4-diazacyclohexane) has been examined in dry dimethyl formamide by spectrophotometric titrations (with Cu2+, Ni2+) to define formation constants, and by stopped-flow kinetics to define the complexation rates and reaction pathway. Initial formation of a rarely observed eta(1)-piperazine intermediate occurs in a rapid second-order reactions. This intermediate then undergoes two competing reactions: formation of (chelated) eta(2)-piperazine (ML) or the formation of (bridging) mu-piperazine (in M2L and M2L3, speciation depending on relative concentrations). Protonation constants and formation constants for complexation in water of N-ethylpiperazine and thiomorpholine (1-aza-4-thiocyclohexane, tm) have been determined by potentiometric titration; 1:1 complexes with first-row M2+ display a log K from similar to 4 to 6, with speciation that suggests chelation of the heterocycles may be involved. Complexation of thiomorpholine has been further probed by the synthesis of Pd-II complexes. The N-monodentate coordination mode has been confirmed in trans-[Pd(tm)(2)Br-2] by an X-ray crystal structure. Complexation of N-(2-aminoethyl)piperazine to Cu-II as a bidentate ligand involving the primary and tertiary amines is also defined by an X-ray crystal structure.
