The formation of benzoxacin-3-ones: Via intramolecular Nicholas reactions and synthesis of 8-membered heliannuols
Green, James R.,St. Onge, Brent

The γ-carbonyl cations generated from propargyl ether-Co2(CO)6 complexes undergo intramolecular Nicholas reactions to give dehydrobenzoxacin-3-one-Co2(CO)6 complexes in good yields. Reductive decomplexation and subsequent manipulation allows the synthesis of (±)-heliannuol K methyl ether and the formal syntheses of (±)-heliannuol K, (±)-heliannuol A, and (-)-heliannuol L.
Pd(II)-catalyzed ortho - Or meta-C-H olefination of phenol derivatives
Dai, Hui-Xiong,Li, Gang,Zhang, Xing-Guo,Stepan, Antonia F.,Yu, Jin-Quan
, p. 7567 - 7571 (2013/06/27)
A combination of weakly coordinating auxiliaries and ligand acceleration allows for the development of both ortho- and meta-selective C-H olefination of phenol derivatives. These reactions demonstrate the feasibility of directing C-H functionalizations when functional groups are distal to target C-H bonds. The meta-C-H functionalization of electron-rich phenol derivatives is unprecedented and orthogonal to previous electrophilic substitution of phenols in terms of regioselectivity. These methods are also applied to functionalize α-phenoxyacetic acids, a fibrate class of drug scaffolds.
