Yap, Connor published the artcileEnantioselective Nickel-Catalyzed Intramolecular Allylic Alkenylations Enabled by Reversible Alkenylnickel E/Z Isomerization, Product Details of C9H12BClO3, the main research area is alkynylallylic phosphate arylboronic acid nickel enantioselective allylic alkenylation isomerization; allylic substitution; asymmetric catalysis; cyclization; isomerization; nickel.

Enantioselective nickel-catalyzed arylative cyclizations of substrates containing a Z-allylic phosphate tethered to an alkyne are described. These reactions give multisubstituted chiral aza- and carbocycles, and are initiated by the addition of an arylboronic acid to the alkyne, followed by cyclization of the resulting alkenylnickel species onto the allylic phosphate. The reversible E/Z isomerization of the alkenylnickel species is essential for the success of the reactions.

Bernardo, Paul H. published the artcileSynthesis of a rhodanine-based compound library targeting Bcl-XL and Mcl-1, Computed Properties of 480438-56-0, the main research area is mol docking anticancer agent rhodanine pyridine amino acid preparation.

Symposium report presented at the 18th International Conference on Organic Synthesis (ICOS) Bergen, Norway 1-6 August, 2010. A small library of pyridine-based rhodanine analogs of BH-3I-1 [i.e., 5-[(4-bromophenyl)methylene]-α-(1-methylethyl)-4-oxo-2-thioxo-3-thiazolidineacetic acid] was designed, the synthesis of the target compound was achieved using amino acids as starting materials and the products thus obtained were screened against B-cell lymphoma (extra large, Bcl-XL, antiapoptotic protein, inhibitor of apoptosis proteins) and myeloid cell leukemia sequence 1 (Mcl-1) for the ability to displace 5-(carboxy)fluorescein-labeled Bak peptide (Flu-Bak). Differences in selectivity toward Bcl-XL and Mcl-1 were observed and the binding modes of selected compounds were studied further. The results may be useful in designing potent small-mol. inhibitors of Bcl-XL and Mcl-1 as well as selective Mcl-1 inhibitors.

The heterogeneous O-arylation of phenols by nitroarenes was achieved in DMF at 100° by using an MCM-41-immobilized bidentate nitrogen copper(II) complex [MCM-41-2N-Cu(OAc)2] as catalyst, yielding a variety of unsym. diaryl ethers I (R1 = 4-OH, 2-OH, 4-NC, etc.; R2 = H, 4-Me, 4-MeO, etc.) in good to excellent yields. This heterogeneous copper catalyst can be easily prepared by a simple procedure from com. readily available and inexpensive reagents, recovered by filtration of the reaction solution and recycled at least seven times without significant loss of activity.

Zheng, Xing-Wang published the artcileThe Coupling of Arylboronic Acids with Nitroarenes Catalyzed by Rhodium, Computed Properties of 61343-99-5, the main research area is diarylether preparation; arylboronic acid nitroarene coupling rhodium catalyst.

The coupling of arylboronic acids with electron-deficient nitroarenes was realized for the first time by using a rhodium(I) catalyst under an air atm., achieving unsym. diaryl ethers, e.g., I with yields ranging from poor to good. From a deuterium labeling experiment, the oxygen atom is derived from ambient water. The efficiency of this reaction was demonstrated by its compatibility with fluoro, bromo, chloro, and trifluoromethyl groups.

Zhang, Jilei published the artcileLigand-free copper-catalyzed coupling of nitroarenes with arylboronic acids, Name: 4-(4-Chlorophenoxy)benzaldehyde, the main research area is ligand free copper catalyzed coupling nitro arene arylboronic acid.

The first example of copper-catalyzed coupling of nitro arenes with arylboronic acids was developed, providing diaryl ethers in moderate to excellent yields. The efficiency of this reaction was demonstrated by compatibility with a wide range of groups. Moreover, the rigorous exclusion of air/moisture is not required in these transformations. Thus, the method represents a simple and facile procedure to access diaryl ethers. Preliminary mechanistic experiments using deuterium labeling showed that the oxygen atom was derived from water.
