Formal syntheses of natural products amorfrutin A, cajaninstilbene acid, hydrangenol, and macrophyllol have been accomplished on the basis of successive C-H bond functionalization of ready-stock benzoic acids. This concise strategy involves transition-metal-catalyzed directed C-H olefination, C-H hydroxylation, and acid-mediated C-H prenylation as key steps.

Flow electrochemistry is an efficient methodology to generate radical intermediates. An electrochemical flow microreactor has been designed and manufactured to improve the efficiency of electrochemical flow reactions. With this device only little or no supporting electrolytes are needed, making processes less costly and enabling easier purification. This is demonstrated by the facile synthesis of amidyl radicals used in intramolecular hydroaminations to produce isoindolinones. The combination with inline mass spectrometry facilitates a much easier combination of chemical steps in a single flow process.

"Chemical Equation Presented" A new cyclization of β-keto ester substituted stilbene derivatives using selenium electrophiles in the presence of Lewis acids is described. Substituted naphthols are obtained through cyclization and subsequent 1,2-rearrangement of aryl groups under very mild reaction conditions.
Diselenide- and disulfide-mediated synthesis of isocoumarins
Shahzad, Sohail A.,Venin, Claire,Wirth, Thomas
experimental part, p. 3465 - 3472 (2010/09/07)
Cyclizations of stilbenecarboxylic acids to the corresponding isocoumarin derivatives using diselenide or disulfide reagents have been developed. By employing bis(triflouroacetoxy)iodobenzene as oxidant for the 6-endo-trig cyclizations a variety of dihydroisocoumarins have been prepared in good yields. This method is capable of forming isocoumarins and dihydroisocoumarin derivatives by a cyclization-elimination route.
