  描述：

  N-amino>-2,2-difluoro-3(S)-amino-6-methylheptanoyl>-L-isoleucyl>-2-pyridylmethylamine 在 1-羟基苯并三唑 作用下， 以 甲醇 为溶剂， 反应 15.0h， 以87%的产率得到{(S)-1-[(S)-1-[(S)-1-((R)-1-Amino-2,2-difluoro-2-{(S)-2-methyl-1-[(pyridin-2-ylmethyl)-carbamoyl]-butylcarbamoyl}-ethyl)-3-methyl-butylcarbamoyl]-2-(1H-imidazol-4-yl)-ethylcarbamoyl]-2-phenyl-ethyl}-carbamic acid tert-butyl ester

  摘要：

  The preparations of sodium 4(S)-[(tert-butyloxycarbonyl)amino]-2,2-difluoro-3(S)- and -3(R)-[(4-methoxyphenyl)amino]-6-methylheptanoates (7a and 7b) from sodium 4(S)-[(tert-butyloxycarbonyl)amino]-2,2-difluoro-3(R)- and -3(S)-hydroxy-6-methylheptanoates (1a and 1b) are described. The key step involves the stereospecific intramolecular displacement via a Mitsunobu reaction for the conversion of a beta-hydroxy hydroxamate to a beta-lactam ring. Compounds 7a and 7b are useful as synthetic intermediates for the preparation of enzyme inhibitors that contain 3(S),4(S)- and 3(R),4(S)-diamino-2,2-difluoro-6-methylheptanoic acid inserts. Angiotensinogen analogues VII and VIII that contain these novel amino analogues of difluorostatine were shown to be inhibitors of the enzyme renin. The alpha,alpha-difluoro-beta-aminodeoxystatine-containing compounds were shown to be weaker inhibitors than the corresponding difluorostatine-containing congeners.
