, p. 2263 - 2265 (2007/10/03)

Gibbilimbols A-D (1-4) were synthesized in 32-49% yield over four steps from commercially available starting materials. A copper-catalyzed coupling of 4-methoxyphenylmagnesium bromide with various unsaturated alkyl bromides was the key step in assembling the (long-chain alkyl)-phenol skeleton.
