Abstract
The description provides processes for the regio and stereospecific synthesis of polyprenylatedquinone derivatives, such as Vitamin K1, K2 and Ubiquinone, exploiting dithioacetals, especially 1,3-dithiane, mediated Umpolung chemistry which works along a new concept 'Inhibiting resonance delocalization (IRD)' to overcome isomerization generated due to delocalization of allyliccarbanion on the π-electron cloud of an allylic systems by the conventional synthesis.
