A new and efficient approach for the synthesis of oxygen and nitrogen heterocycles by organoselenium catalysis has been developed. The exo-cyclization proceeded smoothly under mild conditions with good functional group tolerance and excellent regioselectivity. Mechanistic studies revealed that 1-fluoropyridinium triflate is key for oxidative cyclization.

A simple, iron-based catalytic system allows for the inter- and intramolecular arylation of unactivated secondary alcohols. This transformation expands the substrate scope beyond the previously required activated alcohols and proceeds under mild reaction conditions, tolerating air and moisture. Furthermore, the use of an enantioenriched secondary alcohol provides an enantioenriched product for the intramolecular reaction, thereby offering a convenient approach to nonracemic products.

3-Aryl-2-hydroxycyclopent-2-en-1-ones, when subjected to asymmetric oxidation, result in enantiomerically enriched 2-aryl-5-oxotetrahydrofuran-2- carboxylic acids. Electron-donating substituents in the para position of the phenyl ring increase the yield and decrease the enantioselectivity of the process. Georg Thieme Verlag Stuttgart.
Process for the production of cyclic sulfonium salts
-
, (2008/06/13)
A process for the production of a 5-7 membered ring cyclic sulfonium salt compound, including a 5-7 membered ring cyclic sulfonium salt compound having a non-nucleophilic anion, is described. Members of the latter group are potentially useful as initiators for cationic polymerizations. The process comprises reacting a 1.4-, 1.5-, or 1.6-diol compound or a 5-7 membered ring cyclic ether compound with a mercapto compound and a strong protonic acid yielding the cyclic sulfonium salt compound. Some compounds described are also novel compounds per se.

9-Methylenelongibornane: Lewis Acid-induced Transannular Hydride Shift/Rearrangement to 9-Methylisolongifolene/7-Isopropyl-1,1,3-trimethyltetralin

, p. 40 - 43 (2007/10/02)
9-Methyllongibornyl-9-cation (5, R=Me) generated from 9-methylenelongibornane (2), on exposure to BF3*OEt2 in benzene, has been shown to undergo a transannular 1,5-hydride shift in the "reverse" fashion (C-2 to C-9) to give the crucial 9-methyllongibornyl
