An electrophotochemical ring-opening bromination of unstrainedtert-cycloalkanols has been developed. This electrophotochemical method enables the oxidative transformation of cycloalkanols with 5- to 7-membered rings into synthetically useful ω-bromoketones without the use of chemical oxidants or transition-metal catalysts. Alkoxy radical species would be key intermediates in the present transformation, which generate through homolysis of the O-Br bond in hypobromite intermediates under visible light irradiation.
Palladium-Catalyzed Room-Temperature Acylative Suzuki Coupling of High-Order Aryl Borons with Carboxylic Acids

This note describes a dimethyl dicarbonate-assisted, Pd(OAc)2/PPh3-catalyzed acylative Suzuki coupling of carboxylic acids with diarylborinic acids or tetraarylboronates for practical and efficient synthesis of sterically undemanding aryl ketones at room temperature. More than just cost-effective alternatives to aryl boronic acids, diarylborinic acids and tetraarylboronates displayed higher reactivity in the acylative Suzuki coupling. A variety of alkyl aryl ketones, including those bearing a hydroxy, bromo, or carbonyl group, could be readily obtained in modest to excellent yields.
Synthesis of neuroprotective cyclopentenone prostaglandin analogs: Suppression of manganese-induced apoptosis of PC12 cells
Furuta, Kyoji,Maeda, Masahide,Hirata, Yoko,Shibata, Shoko,Kiuchi, Kazutoshi,Suzuki, Masaaki
, p. 5487 - 5491 (2008/03/13)
The synthesis and evaluation for anti- and proapoptotic properties of cyclopentenone prostaglandin analogs are described. Novel J-type analogs of NEPP11 with a cross-conjugated cyclopentadienone moiety and a lipophilic ω-side chain suppressed manganese io
