Eine einfache Synthese von Rosenfuran und verwandten Verbindungen

3-Methyl-2-geranylfuran (I, R = CH2CH:CMeCH2CH2CH:CMe2, R1 = Me) was prepd. by treating I (R = Li, R1 = Br) [prepd. from I (R = H, R1 = Br) and (Me2CH)2NLi] with BrCH2CH:CMeCH2CH2CH:CMe2 and methylating with MeI in THF contg. BuLi. I (R = CH2CH:CMe2, R1 = Et, Cl, Br, Me; R = Me, CH2CH:CMe2, R1 = H; R = CH2OH, CH2OMe, R1 = Br) were prepd. similarly. [on SciFinder (R)]
