An efficient “one-pot” synthesis of (R)- and (S)-2-bromo-5-phthalimidopentanoic acid from ornithine is described. Subsequent reaction with potassium thiobenzoate affords a concise, scaleable route to (R)- and (S)-enantiomers of 2-benzoylsulfanyl-5-phthalimidopentanoic acid, an intermediate in the synthesis of MMP inhibitors.
描述了从鸟氨酸有效的“一锅”合成(R)-和(S)-2-溴-5-邻苯二甲酰亚胺基戊酸。随后与硫代苯甲酸钾的反应提供了简明的,可规模化的路线,以生成2-苯甲酰基硫烷基-5-邻苯二甲酰亚胺戊酸的(R)和(S)对映异构体,该中间体是MMP抑制剂合成的中间体。
