Other names :
Chroman-2-one ; Benzo dihydro pyrone ; Benzo dihydropyrone ; 1,2-benzodihydropyrone ; Dihydrobenzopyranone ; 2-oxo-chroman ; 2-chromanone ; Dihydro coumarin ; 3,4-dihydro-1-benzopyran-2-one ; Dihydrobenzopyrone ; Hydrocoumarin ; Melilotic acid lactone ; Melilotic lactone ; Melilotine ; Melilotol
Volatility :
Base
Uses in perfumery :
Dihydrocoumarin is not so used in perfumery, but widely used in aromas because Coumarin is not edible. Gives a base to fruity notes, gives a dried fruits note. Used in vanilla flavours, alternating with tonka bean and Peru balsam. Used in white chocolate notes to counterbalance acids.
Natural availability :
Dihydrocoumarin can be extracted in its natural state from several plants, including medicinal tea and Tarragon EO.
Year of discovery :
Data not available.
Other comments :
Dihydrocoumarin does not have a big olfactive difference with Coumarin. This is why it is used as a Coumarin replacer in aromas.

Synthesis route :
Dihydrocoumarin is synthesized from coumarin, by a Raney nickel catalysed hydrogenation reaction. On the other hand, Hexahydrocoumarin can be dehydrogenated during the vapor phase, with a palladium catalysis in order to obtain Dihydrocoumarin.
Synthesis precursor :
Dihydrocoumarin can mediate the synthesis of Hexahydrocoumarin or Octahydrocoumarin. The hydrogenation which allows to obtain these products must be made with the appropriate catalyst and conditions.
Isomerism :
Dihydrocoumarin does not have any isomer used in perfumery.
