Abstract
NEW MATERIAL:Titled compound of the formula (R is H, methyl, ethyl or propyl).
USE: Taste modifier for tobacco.
PREPARATION: Leaves of Turkish tobacco are extracted with isoprpyl ether and the extract is concentrated under reduced pressure. Then the concentrate is subjected to liquid-liquid extraction with a sodution of solium bicarbonate to collect the acid portion. The acid fraction is chromatographed using a column packed with silicic acid in an amount of 20-30 times the weight of the extract and a solvent mix consisting of 98 benzene and 2 methanol. The elucidate is collected and esterified with diazomethane. Then the methyl ester is fractionated by gas chromatography to isolate pure 1-methyl-3-isopropyl-cylcopetane-1,2-dicarboxylic dimethyl ester, from which other compounds are derived.
