Modular Approach to Saturated and α,β-Unsaturated Ketones
摘要:
2-Fluoro-6-pyridinyloxy derivatives of 2-ethoxyvinyl carbinois react with radicals derived from xanthates by an addition fragmentation pathway to give highly functionalized ketones after acid hydrolysis. 1,4-Diketones are readily accessible by this approach. alpha,beta-Unsaturated ketones can be obtained by starting with geminal acetoxy xanthates prepared by addition of a simpler xanthate to vinyl acetate.

Exploiting the reactivity of the novel acetyl (MiDA)boronate radical allows access to a broad range of acyl (MIDA)boronates, which in suitable cases can be converted into B(MIDA) substituted furans and pyrroles.
