A. Abouabdellah et Jt. Welch, OPTICALLY-ACTIVE FLUORINATED BETA-LACTAM BUILDING-BLOCKS - A NOVEL FLUORINATED RETROAMIDE ISOSTERE, Tetrahedron : asymmetry, 5(6), 1994, pp. 1005-1013
A new and versatile synthesis of optically active alpha-fluoro-malonam
ides derivatives from enantiomerically pure 3-fluoro-2-azetidinones is
described. A fluorinated retroamide isostere based on these alpha-flu
oro-malonamide was introduced into a small peptidomimetic for use as a
n HIV-1 protease inhibitor.
