<p>Disclosed is a process for preparing chiral compounds of the formula (I) <IMAGE> (I) wherein: X1 and X2 are independently F or Cl; and E is -SO2R2, wherein R2 is C1-C6 alkyl, -C6H4CH3 or -CF3; its enantiomer and racemates thereof, useful in the synthesis of tetrahydrofuran azole antifungals. Novel compounds of the formula <IMAGE> or <IMAGE> wherein: X1 and X2 are independently F or Cl; B represents -C(O)Q* or -CH2OR''; Q* represents a chiral auxiliary group; R'' represents a hydroxy protecting group selected from -CH2C6H5, or -C(O)R1, wherein R1 is C1-C6 alkyl; and A represents Cl, Br, I or triazolyl; are also disclosed.</p> |
