Organic letters

Peng Y, Xiao J, Xu XB, Duan SM, Ren L, Shao YL, Wang YW.
PMID: 27658859
Org Lett. 2016 Oct 07;18(19):5170-5173. doi: 10.1021/acs.orglett.6b02665. Epub 2016 Sep 23.

A Ni-mediated cascade to a stereoselective synthesis of trans-tetrahydronaphtho[2,3-b]furans is efficiently achieved for the first time. The mild reductive system can be easily generated from inexpensive and air-stable materials and shows a broad positional tolerance of substituents that were...

Beilstein J Org Chem. 2015 May 29;11:906-12. doi: 10.3762/bjoc.11.102. eCollection 2015.

The carboxylative cyclization of o-hydroxy- and o-acetamidoacetophenone with carbon dioxide promoted by the organic base 1,8-diazabicycloundec-7-ene (DBU) is reported. This reaction provides convenient access to the biologically important compounds 4-hydroxy-2H-chromen-2-one and 4-hydroxy-2(1H)-quinolinone in moderate to good yields using carbon...

The cross-coupling reaction of allyl boron ester with 1°/2°/3°-halogenated alkanes in the presence of copper has been developed for the first time, which provides a mild and efficient method for the construction of saturated C(sp(3))-C(sp(3)) bonds. This protocol shows...

Pore space partition by symmetry-matching regulated ligand insertion and dramatic tuning on carbon dioxide uptake.

Journal of the American Chemical Society

Zhao X, Bu X, Zhai QG, Tran H, Feng P.
PMID: 25621414
J Am Chem Soc. 2015 Feb 04;137(4):1396-9. doi: 10.1021/ja512137t. Epub 2015 Jan 26.

Metal-organic frameworks (MOFs) with the highest CO(2) uptake capacity are usually those equipped with open metal sites. Here we seek alternative strategies and mechanisms for developing high-performance CO(2) adsorbents. We demonstrate that through a ligand insertion pore space partition...

Off-pump coronary artery bypass graft (CABG) surgery has recently emerged as a means to avoid the sequelae of extracorporeal circulation, including the whole-body inflammatory response, coagulation disorders and multiple organ dysfunction. At present, gas anesthesia, sevoflurane and intravenous anesthesia...

Serum thymidine kinase 1 levels correlate with clinical characteristics of esophageal squamous cell carcinoma.
