is a key reaction for the synthesis of a homostatine analogue. Stereoselective and stereospecific syntheses of a N-terminal precursor, N-[(2R)-3-hydroxy-2-(1-naphthylmethyl)propionyl]-L-norleucine t-butyl ester and a total synthesis of a highly active renin inhibitor, (2RS,4S,5S)-N-isobutyl-5-[[N-[(2S)-2-(1-naphthylmethyl)-3-(2-pyrimidinylsulfonyl)propionyl]-L-norleucyl]amino]-2-ethyl-4-hydroxy-7-methyloctanamide
以天然他汀为原料合成了一种高抑素类似物 (2RS,4S,5S)N-isobutyl-5-amino-2-ethyl-4-hydroxy-7-methyloctanamide。(4S,5R)-3-benzyloxycarbonyl-5-formyl-4-isobutyl-2,2-二甲基恶唑烷的改良 Horner-Wadsworth-Emmons 反应是合成高抑素类似物的关键反应。N-末端前体的立体选择性和立体特异性合成,N-[(2R)-3-羟基-2-(1-萘基甲基)丙酰基]-L-正亮氨酸叔丁酯和高活性肾素抑制剂的全合成, (2RS,4S,5S)-N-isobutyl-5-[[N-[(2S)-2-(1-naphthylmethyl)-3-(2-pyrimidinylsulfonyl)propionyl]-L-norleucyl]amino]-2-描述了乙基-4-羟基-7-甲基辛酰胺。
