Synthesis of (2S)-4,4-difluoroproline, (2S,4R)-4-fluoroproline and their derivatives from (S)-aspartic acid [1]
摘要:
Syntheses for (2S)-4,4-difluoroproline, (2S,4R)-4-fluoroproline and their derivatives are described starting from (S)-aspartic acid, using hexafluoroacetone as the protecting reagent and DAST as the fluorinating agent.
