Copper-Catalyzed anti-Selective Radical 1,2-Alkylarylation of Terminal Alkynes

A copper-catalyzed highly anti-selective radical 1,2-alkylarylation of terminal alkynes with aryl boronic acids and alkyl bromides has been established. The reaction exhibits high compatibility with a wide range of terminal alkynes and diverse aryl boronic acids, thus providing facile access to various stereodefined trisubstituted alkenes in high yield under mild reaction conditions. Preliminary mechanistic investigations support the formation of alkyl radicals and their subsequent addition to alkynes in the reaction.

New results on the triplet photoreactivity of β,γ-unsaturated aldehydes: Diastereoselective synthesis of cyclopropanecarbaldehydes

A comparative study on the triplet photoreactivity of a series of β,γ-unsaturated aldehydes and methyl ketones has been carried out. Aldehydes 14 and 20 were found to undergo the oxa-di-π-methane rearrangement yielding the corresponding cyclopropane carbaldehydes 15 and 21 diastereoselectively. Decarbonylations and 1,3-carbonyl migrations have been observed in some cases, although these reactions do not take place via a Norrish Type I mechanism.
