In situ Reduction in Photocycloadditions: A Method to Prevent Secondary Photoreactions
摘要:
Secondary photoreactions are a common cause for the low yields often observed in photochemical reactions, preventing their widespread deployment in synthesis. In situ reductions which remove the chromophore from the product as it is formed provide a convenient method to prevent these secondary photoreactions.
Reactivity of tris(trimethylsilyl)silyl radical with β-alkenyloxyenones
摘要:
The addition of tris(trimethylsilyl)silyl radical on beta-alkenyloxyenones generates an alkyl radical that can add onto the enone moiety. The tetrahydrofuranyl system so-obtained can undergo beta-elimination leading to 3-alkylcycloalken-2-ones.
