| Product | methyl (+)-(1R,2S,3R)-3-hydroxy-2-pentyl-1-cyclopentaneacetate | HCID 7075801 | — |
Reaction Steps
It is to be noted that (+)-(1R,2S,3R)-3-hydroxy-2-pentyl-1-cyclopentaneacetic acid, used as starting product in this variant of the process of the invention, can also be directly methylated, for example by reacting it with an excess of diazomethane in ether solution, to provide pratically pure methyl (+)-(1R,2S,3R)-3-hydroxy-2-pentyl-1-cyclopentaneacetate, which can then be converted into (+)-cis-Hedione® via oxidation.
