REACTION OF XeF2. PART 7. SYNTHESIS OF 6-FLUOROBIOTIN METHYL ESTER

The synthesis of 6-fluoro-d-biotin methyl ester and its characterization by (1)H and (19)F nmr and elemental analysis is described.Analogous reactions of XeF2 with tetramisole and benzylpenicillin methyl ester were carried out but monofluorinated products
