Abstract
NEW MATERIAL:A hydroquinone derivative of formula I (X1 and X2 are lower alkyls, or lower alkoxyls, or together may form formula II).
EXAMPLE: 2,3-Dimethoxy-5-methyl-1,4-hydroquinone-di-tetrahydrofuryl ether.
USE: A synthetic intermediate for medicines, e.g. vitamin K (when X1 and X2 in formula I are formula II) or coenzyme Q (when X1 and X2 in formula I are methoxys).
PROCESS: A substituted hydroquinone of formula III is reacted with 2,3-dihydrofuran in the presence of an acidic catalyst, e.g. pyridinium p-toluenesulfonate, in a solvent, preferably in an inert gas atmosphere e.g. N2, at 10W20°C to give the compound of formula I.
