Semi-synthesis and antitumor activity of 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives

We recently discovered that 5, 8-O-dimethyl acylshikonin derivatives displayed the selectivity towards MCF-7 and no toxicity to normal cells. Herein, a series of the corresponding 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were synthesized starting from shikonin. In vitro evidence of the cytotoxicities indicated that most of thecompounds were more active than or comparative to shikonin and retained the selectivity against MCF-7, MDA-MB-231 besides no toxicity in the normal cells. Also, in vivo anticancer activity of the positional isomers 5p, 6c further showed that 6-isomers of 5, 8-O-dimethyl acylshikonin derivatives were more active than their corresponding 2-isomers. Thus, we may conclude that the position of the side chain of shikonin attached to 5,8-dimethoxy -1,4-naphthoquinone is associated with the antitumor activity.

Synthesis and characterization of an 8-membered ringlet and a novel sodium organotin carboxylic polymer

Two organotin complexes of two types were synthesized by different methods basing on the same materials. Characterizations of the complexes were achieved by elemental analysis, IR, NMR (1H, 13C and 119Sn) spectroscopy and X-ray crystallography diffraction analysis. X-ray data reveal that complex 1 is an 8-membered cycle and complex 2 is a surprising mixed sodium organotin carboxylic polymer, in which the sodium atom shows its ability to act as a heptacoordinated atom. It is worth to note that X-ray diffraction study reveals that complex 1 crystallizes in the triclinic space group P1, which is chiral space group.

Enantio-differentiating hydrogenation of methyl 2-furoylacetate and its analogs over tartaric acid-modified Raney nickel

Hydrogenation of methyl 2-furoylacetate over TA-MRNi reduced the three unsaturated bonds to give methyl tetrahydro-2-furoylacetate, the enantiomeric excess (ee) of which at the 3-position was 77%, whereas the 4-position was racemic. Under the same conditions, the substrate of 4-methoxycarbonyl analogue was resulted in hydrogenation of only the ketone moiety to give the corresponding chiral sec-alcohol having a furan ring in 69% ee.

Oxidation of partially protected carbohydrates at the nickel hydroxide electrode

Primary hydroxy groups in pyranoses are oxidized in excellent yields to the corresponding carboxylic acids. In furanose 3 the yield of acid is only moderate. Secondary hydroxy groups are inert, aside from lactols. The different reactivity of secondary and primary hydroxy groups allows the chemoselective oxidation of 8 and 10.

Influence of outer-sphere anions in europium tetrahydrofuran-2-carboxylates on the Eu3+ luminescence center, analyzed by methods of X-ray diffraction and optical spectroscopy

Five new lanthanide tetrahydrofuran-2-carboxylate (THFC) complexes [Ln(THFC)2(H2O)2]¡¤L¡¤H 2O (Ln = Eu; L = Cl-, Br-, NO3 – and Ln = Tb; L = Cl-, NO3-) have been synthesized. The crystal structures of four compounds were solved by the X-ray diffraction method. The Ln3+ ions are coordinated to eight oxygen atoms: six oxygen atoms are provided by two tridentate bridging-cyclic THFC ligands, and the other two by water molecules. The Ln3+ coordination polyhedron can be described as a distorted square antiprism. The structures consist of planar layers linked by hydrogen bonds through outer-sphere L anions and H2O molecules. The influence of the L anion on the Eu3+ luminescence center is analyzed with the help of luminescence and IR vibrational spectroscopy. The distortions of the square antiprism increase with the size of the L outer-sphere anions. Consequently, the lowering of the symmetry of the crystal field around the Eu3+ ion appears as an extra splitting of the 7FJ levels under the influence of the crystal field components of the second and fourth ranks.

Room-Temperature Decarboxylative Alkynylation of Carboxylic Acids Using Photoredox Catalysis and EBX Reagents

Alkynes are used as building blocks in synthetic and medicinal chemistry, chemical biology, and materials science. Therefore, efficient methods for their synthesis are the subject of intensive research. Herein, we report the direct synthesis of alkynes from readily available carboxylic acids at room temperature under visible-light irradiation. The combination of an iridium photocatalyst with ethynylbenziodoxolone (EBX) reagents allowed the decarboxylative alkynylation of carboxylic acids in good yields under mild conditions. The method could be applied to silyl-, aryl-, and alkyl- substituted alkynes. It was particularly successful in the case of alpha-amino and alpha-oxo acids derived from biomass.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 166591-85-1, help many people in the next few years.Recommanded Product: 166591-85-1

One-pot transition-metal-free synthesis of weinreb amides directly from carboxylic acids

Weinreb amides were prepared directly from carboxylic acids, N,O-dimethylhydroxylamine, and phosphorus trichloride in one pot at 60 C in toluene in high yields, thus avoiding the separation of the moisture and air sensitive intermediate P[NMe(OMe)]3 in advance. Sterically hindered carboxylic acids also give the corresponding Weinreb amides in excellent yields. Various functional groups are tolerated on the carboxylic acid. The method, which is a simple process and gives high yields, is suitable for large-scale production. Georg Thieme Verlag KG Stuttgart ¡¤ New York.

Decarboxylative alkynylation and cyanation of carboxylic acids using photoredox catalysis and hypervalent iodine reagents

Alkynes and nitriles are important functional groups that serve as versatile building blocks in organic synthesis and find applications in material and medicinal sciences. A convenient and straightforward access to both classes of compounds under mild conditions is, therefore, highly desirable. Herein, we disclose the decarb-oxylative alkynylation and cyanation of broadly available carboxylic acids using photoredox catalysis and hyper-valent iodine reagents. Choices of both catalysts and reagents were crucial. Computational and experimental studies revealed two different possible mechanisms that are dictated by the oxidation potential of the reagents: radical for alkynylation, ionic for cyanation.
