Ampelocalamus scandens is native to Guizhou Province, China, and grows at an altitude of 260-320 m. It can be used as a raw material for weaving and papermaking. In the current study, the complete chloroplast (cp) genome of A. scandens was sequenced and is reported for the first time. The complete cp sequence was 139,504 bp, include large single-copy (LSC), small single-copy (SSC), and a pair of invert repeats (IR) region of 83,103 bp, 12,813 bp, and 21,793 bp, respectively. Besides, the plastid genome comprised a total of 132 genes, including protein-coding, tRNA, and rRNA genes as 85, 39, and 8 genes, respectively. Phylogenetic analysis based on 28 cp genomes reveals that A. scandens is closely associated with Ampelocalamus melicoideus in Arundinarodae.

Three novel mixed ligand Zn(II) complexes {complex 1 = [Zn(L1)(2)(bpy)], complex 2 = [Zn(L2)(2)(bPY)], complex 3 = [Zn(L2)(2)(phen)], where bpy = 2,2′-bipyridine and phen = 1,10-phenanthroline} of 4-(4-chlorobenzoyl)-2-(3-chlorophenyl)-5-methyl-2,4-dihydro-3H-pyrazol-3-one (HL1) and 4-(4-chlorobenzoyl)-5-methyl-2-(p-tolyl)-2,4-dihydro-3H-pyrazol-3-one (HL2) were synthesized and characterized by H-1 and C-13 NMR, FTIR, TG-DTA, UV-Vis, elemental analysis, molar conductance and single crystal X-ray structure determination. Based on analytical and spectroscopic techniques, all the three Zn(II) complexes were found to have a distorted octahedral geometry. The ligands and the complexes were screened for antimalarial activity against plasmodium falciparum. The zinc(II) complexes showed greater antimalarial activity than their parent ligands.

Dearomatization of indole derivatives offers a straightforward approach to access diverse indolines. To date, the corresponding dearomative transformations involving electron-deficient indoles are limited. Herein, we report a one-electron strategy for dearomatization of electron-deficient indoles via a photoredox-catalyzed hydroalkylation employing commercially available glycine derivatives as the hydrofunctionalization reagents. Followed by DBU-mediated lactamization, structurally appealing lactam-fused indolines are obtained in good to excellent yields with exclusive selectivity.

In this letter, an efficient one-pot asymmetric sequential reaction is achieved by organo/transition metal relay catalysis in constructing two consecutive C-C bonds, which involves enantioselective amino squaramide catalytic Mannich-type addition of pyrazolones to isatin-derived ketimines and a subsequent palladium catalyzed diastereoselective allylic alkylation of pyrazolones with allylic acetates. An array of novel pyrazolone-aminooxindole-propylene structural motifs are obtained in a high level of yield and with excellent enantio- and diastereoselectivity (up to 95% yield, >20:1 dr, >99% ee). This methodology features the formation of vicinal quarternary carbon-stereocenters, and the second all-carbon tetrasubstituted stereogenic center is induced by joint action of the achiral palladium catalysis and the chiral environment generated from the Mannich step. Moreover, the usefulness of this methodology is highlighted by converting the allylic product into the carbonyl compound.

A cobalt-catalyzed regio- and enantioselective gamma-amination of beta,gamma-unsaturated N-acylpyrazoles that delivers the corresponding gamma-amination products in good regio- and enantioselectivity has been established. Moreover, the nitrogen-containing compounds could be easily synthesized. DFT calculations have been provided to explain regio- and enantioselectivity for this gamma-amination. The chiral gamma-amination products were readily converted into the chiral gamma-amino acid derivatives.

A series of pyrazole ligands named as 1,4-bis(3,5-dimethylpyrazol-1-yl)butane (bbd), 1,3-bis(3,5-dimethylpyrazol-1-yl)propane (bdpp), and 1,3-bis(3,5-dimethylpyrazol-1-yl)propane-2-ol (bdpo) along with their transition metal complexes including [Cu-2(mu(3)-SCN)(2)(mu-bbd)](n), [Cu-2(mu(3)-SCN)(2)(mu-bdpp)](n), and [Cu2Hg(mu(2)-SCN)(2)(bdpo)(2)(CH3COO)(2)](n)were synthesized and characterized using FT-IR and Uv-vis spectroscopies, as well as thermal gravimetric analysis. The prepared compounds were investigated as corrosion inhibitors to protect mild steel in 0.5 M H(2)SO(4)solution. Corrosion tests were performed by electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The pyrazole ligands exhibited inhibition efficiencies in a range of 38-78%, which introduced them as moderate inhibitors. On the other hand, the pyrazole complexes showed inhibition efficiencies higher than 85%, demonstrating their high potentials to mitigate the steel corrosion. In addition, the bimetallic complex resulted in higher corrosion resistance than the two monometallic complexes. This was evidence of a critical role of the coordinated metal of the complex in forming an adhesive protection film on the steel surface.

An efficient and straightforward method for the synthesis of new and versatile sulfonyl-functionalized allylic amines through the selective copper-catalyzed aza-1,6-conjugate addition of heterocycles or arylamines to 1,4-disubstituted-1,3-dienyl sulfones has been developed. This catalytic process is promoted by a combination of an easily prepared and sterically demanding N-heterocyclic carbene-based copper complex and KOt-Bu under mild reaction conditions to provide a broad range of (E)-allylic amines with excellent regio- and stereoselectivities.
