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.
