Abstract

Przedmiotem zgłoszenia jest związek o nazwie: (+)-rel-(1R,6R,1'R)-1-(1'-Bromoetylo)-9-oksabicyklo[4.3.0]nonan-8-on o wzorze 2, przedstawionym na rysunku. Zgłoszenie obejmuje też sposób otrzymywania(+)-rel-(1R,6R,1'R)-1-(1'-bromoetylo)-9-oksabicyklo[4.3.0]nonan-8-onu, polegający na tym, że kwas (+)-(2'-etylideno-cykloheksylo)octowy o wzorze 1 poddaje się reakcji bromolaktonizacji w której otrzymuje się (+)-rel-(1R,6R,1'R)-1-(1'-Bromoetylo)-9-oksabicyklo[4.3.0]nonan-8-on o wzorze 2, który oczyszcza się metodą chromatografii kolumnowej.The subject of the application is a compound named: (+) - rel- (1R, 6R, 1'R) -1- (1'-Bromoethyl) -9-oxabicyclo [4.3.0] nonan-8-one of the formula 2, shown in the drawing. The application also covers a method for the preparation of (+) - rel- (1R, 6R, 1'R) -1- (1'-bromoethyl) -9-oxabicyclo [4.3.0] nonan-8-one, which consists in the fact that the acid The (+) - (2'-ethylidene-cyclohexyl) acetic acid of formula 1 is subjected to a bromolactonization reaction to obtain (+) - rel- (1R, 6R, 1'R) -1- (1'-Bromoethyl) -9 -oxabicyclo [4.3.0] nonan-8-one of formula 2 which is purified by column chromatography.
