trans-2-methyl cyclopentanol acetateRosa setate var. rugosaPerflavory
Evaporation of the methanol left 2α-carboxymethyl-3β-nitromethyl-4α-methoxycarbonylcyclope ntanol as a liquid residue which was extracted with a 20% by volume acetone in 80% ethyl acetate solution. The solution was dried and the solvent removed under reduced pressure. The residue was then ...
