4,5,5-trimethyloxolan-2-one

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

实验步骤: Using a method similar to Example 1, 172 parts of methyl 4-formyl-3,4-dimethyl-valerate are reacted with 80 parts of oxygen in the course of 4 hours. 91 parts (71% of theory) of β,γ,γ-trimethyl-γ-butyrolactone (boiling point 94°-96° C./16 mbar) are obtained.
