Process for preparing chroman derivatives |
| abstract |
Preparation of chroman derivatives (I) <IMAGE> (R¹-R³ = H, C1-C8-alkyl; R <4> = H, C1-C8-alkyl or acyl; R <5> = C1-C8-alkyl), by a hydroquinone (II) <IMAGE> with a Lewis acid or a similarly acting Lewis acid derivative in the presence of an inert solvent with a nitrile (CH2 = CH-C (R <5>) (OR <6>) CN; III; R <6 > = H, C1-C4-acyl or alkyl) or with compounds from which III is formed in situ. |
