合成路线1
该中间体在本合成路线中的序号:(V)The reductive condensation of N-Boc-L-isoleucinal (I) with glycine methyl ester (II) using sodium triacetoxyborohydride afforded secondary amine (III), which was further reductively condensed with 1-naphthaldehyde (IV), yielding tertiary amine (V). After basic hydrolysis of the methyl ester group of (V), the resulting carboxylic acid (VI) was coupled with L-methionine methyl ester (VII) by means of EDC and HOBt to give peptide (VIII). Subsequent deprotection of the Boc group of (VII) with HCl in cold EtOAc furnished the required intermediate (IX).
