supporting information; experimental part, p. 406 - 409 (2011/04/18)
The electrochemical reduction of diphenylphosphinate esters leads smoothly and in high yields to the corresponding deoxygenated products. In comparison with the previously developed methodologies, the electrolysis could be performed at lower temperature and with a higher current density, resulting in a shorter reaction time.

A typical π-acid tetracyanoethylene and capto-dative olefin dicyanoketene acetals were found to catalyze stereospecific alcoholysis of epoxides at the ambient temperature to 50°C in good yields. Mildness and significant chemoselectivity of the catalysts were demonstrated by intactness of tetrahydropyranyl ether and ethylene acetal groups. A novel regioselectivity associated with anchimeric assistance of the ethereal group on the side chain was observed in the ring opening reaction of the 1,2-disubstituted epoxides.

Hexahydrobenzofurans were prepared through Bu3SnH radical cyclization of propargyloxy cyclohexanone precursors.Good results were obtained for monosubstituted acetylenic derivatives after conversion of the carbonyl group into the corresponding enol ether.U
