(R)-(-)-N-(2,3-Epoxypropyl)phthalimide → 2-[(2r)-3-Fluoro-2-hydroxypropyl]-1h-isoindole-1,3-dione

Participants

Reaction Steps

A sample of 2-[(2R)-Oxiranylmethyl]-1H-isoindole-1,3-dione (G. Alexander et al. Tetrahedron Asymmetry, 7, 1641-8, 1996) is treated with potassium hydrogen difluoride to give 2-[(2R)-3-fluoro-2-hydroxypropyl]-1H-isoindole-1,3-dione in the presence of catalyst nBu4NH2F3. The procedures and methods used in this synthesis are identical to those of Example 3, except that in step Example-3B 2-[(2R)-3-fluoro-2-hydroxypropyl]-1H-isoindole-1,3-dione is used instead of (S)-1-[(benzyloxycarbonyl)amino]-2-propanol to produce the title product.
