a-戊基肉桂醛

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 150 g of 4,8-dimethyl-3,7-nonadien-2-ol, 252.5 g alpha-amylcinnamaldehyde and 16.9 g of aluminum isopropoxide are refluxed for 30 min at 1 mbar. A product/reactant mixture is then distilled over a 15 cm packed column (reflux ratio 1:1). This gives 130 g of the mixture of E- and Z-4,8-dimethyl-3,7-nonadien-2-ol and E- and Z-4,8-dimethyl-3,7-nonadien-2-one . The sum of the two isomers of 4,8-dimethyl-3,7-nonadien-2-ol is 23%, and the sum of the two isomers of 4,8-dimethyl-3,7-nonadien-2-one is 70%. A product/reactant mixture is then distilled over a 15 cm column (reflux ratio 1:1)
