Optically active fluorinated β-lactam building blocks: A novel fluorinated retroamide isostere.
摘要:
A new and versatile synthesis of optically active alpha-fluoro-malonamides derivatives from enantiomerically pure 3-fluoro-2-azetidinones is described. A fluorinated retroamide isostere based on these alpha-fluoro-malonamide was introduced into a small peptidomimetic for use as an HIV-1 protease inhibitor.
