Organic Lewis Acids, 331) The Photochemistry of Cyclic Acylals of Alkylidene-, Alkenylidene-, and Benzylidenemalonic AcidsThe photochemistry of the title compounds 1 resembles that of α,β-unsaturated esters. Observed reactions include deconjugation (→ 2), β, δ-cyclopropane ring closure(→ 4), and [2 + 2]-cycloaddition (→ 5, 7, 8) as well as ene-type addition to olefins (→ 9). Reaction mechanism and preparative aspects are discussed.
Notes:
Die Photochemie der Titelverbindungen 1 entspricht der von α,β-ungesättigten Estern: Dekonjugation zu 2, β,δ-Cyclopropanbildung (→ 4) und [2 + 2]-Cycloaddition (→ 5, 7, 8) sowie substituierende Addition an Olefine (→ 9) Reaktionsmechanismus und präparative Aspekte werden diskutiert.
