Process for the preparation of cis-6,6-dimethyl-3-oxabicyclo [3.1.0] hexan-2-one \ t |
| abstract |
The present invention relates to a process for the preparation of cis-6,6-dimethyl-3-oxabicyclo [3.1.0] hexan-2-one by: (a)? the? -butyrolactone sulfonic acid ester is reacted in a solvent with a compound of the formula M (1-6C) alkoxide? or (b) a (1-4C) alkyl ester of 4,5-epoxy-3,3-dimethylpentanecarboxylic acid in a solvent is reacted with a compound of formula M (C 1-6 alkoxide) y - in which M represents a cation and y represents a number corresponding to its cationic value. ŕ |
