Claim Text:
1. A method for synthesis of polyprenylated quinone derivatives comprising regiospecific and stereospecific synthesis of compound of formula I wherein n=an integer from 0 to 8, R=is independently selected from —CH═CH—CH═CH—, wherein both R groups form a naphthalene ring and OCH3; and the said method comprising the steps of providing a dithioacetal derivative selected from the group of quinones (II), prenols (V) and combinations thereof, wherein m=2 or 3; n=is an integer from 0 to 8; R=—CH═CH—CH═CH—, wherein both R groups form a naphthalene ring or OCH R R the said derivatives participating in a reaction with halides of respective counter synthon of formula III or IV, wherein R=—CH═CH—CH═CH—, wherein both R groups form a naphthalene ring or OCH R X=OMs, Br, Cl, I, OTs.
