合成路线1
该中间体在本合成路线中的序号：(V)The reductocondensation of ethyl glycinate (I) with 2-indanone (II) by means of sodium cyanoborohydride in methanol gives ethyl N-(2-indanyl)glycinate (III), which is condensed with N-benzyloxycarbonyl-L-alanine (IV) by means of isobutyl chlorocarbonate and triethylamine in THF yielding N-(N-benzyloxycarbonyl-L-alanyl)-N-(2-indanyl)glycine ethyl ester (V). The partial hydrolysis of (V) with NaOH in methanol affords N-(N-benzyloxycarbonyl-L-alanyl)-N-(2-indanyl)glycine (VI), which is deprotected by hydrogenolysis with H2 over Pd/C in ethanol giving N-(L-alanyl)-N-(2-indanyl)glycine (VII). Finally, this compound is reductocondensed with ethyl 2-oxo-4-phenylbutanoate (VIII) by means of sodium cyanoborohydride in ethanol.
