合成路线1
该中间体在本合成路线中的序号：(II)The reaction of (S)-linalool (I) with 2,4,4,6-tetrabromocyclohexa-2,5-dienone (TBCO) in nitromethane gives a mixture of tetrahydrofuran (II) and tetrahydropyran (III), which are separated by chromatography. The vinyl group of (III) is oxidized with OsO4 and NaIO4, yielding a diastereomeric mixture of aldehydes that is separated by chromatography to afford the target aldehydic intermediate (IV).
