Synthesis of some new biheterocycles by a one-pot Suzuki-Miyaura coupling reaction
Deodhar, Mandar,Black, David Stc.,Shiu-Hin Chan, Daniel,Kumar, Naresh
, p. 1267 - 1274 (2010)
Halogenated indoles, benzofurans and flavones were subjected to a one-pot Suzuki-Miyaura coupling reaction to generate a series of new biheterocycles. The methodology may be readily adapted to the synthesis of a wide variety of substituted biheterocycles.

Targeted covalent inhibitors have re-emerged as validated drugs to overcome acquired resistance in cancer treatment. Herein, by using a carbonyl boronic acid (CBA) warhead, we report the structure-based design of BCR-ABL inhibitors via reversible covalent targeting of the catalytic lysine with improved potency against both wild-type and mutant ABL kinases, especially ABLT315I bearing the gatekeeper residue mutation. We show the evolutionarily conserved lysine can be targeted selectively, and the selectivity depends largely on molecular recognition of the non-covalent pharmacophore in this class of inhibitors, probably due to the moderate reactivity of the warhead. We report the first co-crystal structures of covalent inhibitor-ABL kinase domain complexes, providing insights into the interaction of this warhead with the catalytic lysine. We also employed label-free mass spectrometry to evaluate off-targets of our compounds at proteome-wide level in different mammalian cells.
Palladium-Catalzyed Atroposelective 16-Membered Macrocyclization: Total Synthesis of Isoplagiochin D?

Isoplagiochin D is a ring-strained macrocyclic bisbibenzylis, which showed stable axial chirality in one biaryl structure, and semistable axial chirality in the other biaryl moiety. We reported here an unprecedented example for the catalytically asymmetri
Ortho-Selective C-H Borylation of Aromatic Ethers with Pinacol-borane by Organo Rare-Earth Catalysts
Xue, Can,Luo, Yong,Teng, Huailong,Ma, Yuanhong,Nishiura, Masayoshi,Hou, Zhaomin

The regioselective C-H borylation of aromatic ethers such as anisoles is of much interest and importance, but has remained a challenge to date. We report herein the catalytic ortho-selective C-H borylation of a wide range of aromatic ethers with pinacolborane (HBpin) by rare-earth metallocene complexes. This protocol offers an efficient and straightforward route for the synthesis of a variety of borylated aromatic ether derivatives. A proper metal/ligand combination for the rare-earth metal catalysts was found to be critically important to promote this transformation.

The present invention relates to certain substituted bicyclic compounds that are agonists of RXR and which are therefore useful in the treatment of certain disorders that can be prevented or treated by activation of this receptor. In addition the invention relates to the compounds, methods for their preparation, pharmaceutical compositions containing the compounds and the uses of these compounds in the treatment of certain disorders.
Formal Ir-Catalyzed Ligand-Enabled Ortho and Meta Borylation of Aromatic Aldehydes via in Situ-Generated Imines
Bisht, Ranjana,Chattopadhyay, Buddhadeb
supporting information, p. 84 - 87 (2016/01/25)
The ligand-enabled development of ortho and meta C-H borylation of aromatic aldehydes is reported. It was envisaged that while ortho borylation could be achieved using tert-butylamine as the traceless protecting/directing group, meta borylation proceeds via an electrostatic interaction and a secondary interaction between the ligand of the catalyst and the substrate. These ligand-substrate electrostatic interactions and secondary B-N interactions provide an unprecedented controlling factor for meta-selective C-H activation/borylation.

Total synthesis of acerogenins E, G and K, and centrolobol
Ogura, Tetsuhiro,Usuki, Toyonobu
, p. 2807 - 2815 (2013/03/28)
The first total synthesis of the diarylheptanoid acerogenins E and K, isolated from Acer nikoense MAXIM., is described. Formation of the 13-membered m,m-cyclophane skeleton was successfully achieved on the basis of a domino process involving a Miyaura arylborylation-intramolecular Suzuki reaction. The cyclization precursor was prepared via a Wittig reaction and Claisen-Schmidt condensation, which proceeded in moderate yields. The total synthesis of acerogenin G and centrolobol was also achieved from a common synthetic intermediate.
