3a,4,5,6,7,7a-hexahydro-1,3-benzodioxol-2-one

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into 10 g (86 mmol) of trans-1,2-cyclohexanediol (CAS No. 1460-57-7) and 87.7 g (86 mmol) of dimethyl carbonate was added 0.5 g (9 mmol) of sodium methoxide. The resulting mixture was refluxed for 1 hour. After methanol was removed from the mixture, rectification was carried out. A purified hexahydro-1,3-benzodioxol-2-one (trans isomer) was recovered with a yield of 93%. The resulting mixture was refluxed for 1 hour After methanol was removed from the mixture, rectification A purified hexahydro-1,3-benzodioxol-2-one (trans isomer) was recovered with a yield of 93%
