P. Bravo et al., ASYMMETRIC-SYNTHESIS OF ENANTIOMERICALLY PURE 4'-FLUOROALKYL-2',3'-DIDEOXY NUCLEOSIDES, Bioorganic & medicinal chemistry letters, 4(13), 1994, pp. 1577-1580
Elaboration of (fluoromethyl)-2-[(4-methylphenylsulphinyl)methyl] oxir
ane (5), deriving from p-tolylmethyl sulphoxide (2), ethyl fluoroaceta
te (3) and diazomethane, to 4'-fluoromethyl lactol (10) followed by co
ndensation with the activated thymine and reductive debenzylation allo
wed the obtainment of 4'-fluoromethyl-2',3'-dideoxythymidine (1).
