Process for producing 6-methyl-3-hepten-2-one and 6-methyl-2-heptanone analogues, and process for producing phyton or isophytol |
摘要 |
Provided are a process for producing 6-methyl-3-hepten-2-one by cross aldol condensation carried out while each continuously adding to acetone, isovaleraldehyde and an aqueous alkali containing an alkaline substance; a process for producing a 6-methyl-2-heptanone analogue represented by Formula (1): wherein n is an integer of 0 or 1 or more; which comprises allowing hydrogen, acetone and an aldehyde represented by Formula (2): wherein n is as defined above; X and Y each represents a hydrogen atom or they are coupled together to form a carbon-carbon bond; and Z and W each represents a hydrogen atom or they are coupled together to form a carbon-carbon bond; to react in the presence of an aqueous alkali containing an alkaline substance, and a hydrogenation catalyst; and a process for producing phyton or isophytol using the 6-methyl -3-hepten-2-one or the 6-methyl-2-heptanone analogue.
