Process for producing coumarin derivatives |
| abstract |
A process for producing a coumarin derivative represented by formula (II): ##STR1## wherein R 1 to R 4 are as defined in the specification, comprising the step of: subjecting to a ring formation and dehydrogenation reaction a 3-(2-cyclohexanoyl)-propionic acid ester derivative represented by formula (I): ##STR2## wherein R 1 to R 4 are as defined in the specification, the ring formation and dehydrogenation reaction being (1) conducted by use of a catalyst comprising a carrier having supported thereon palladium and either of chromium oxide and chromium hydroxide, or (2) conducted by use of a catalyst comprising a carrier having supported thereon palladium or a catalyst comprising a carrier having supported thereon palladium and either of chromium oxide and chromium hydroxide, in the presence of a promoter which is at least one member selected from the group consisting of magnesium trisilicate, zirconia, metallic chromium, and metallic tungsten. |
