合成路线1

该中间体在本合成路线中的序号：(VII)

Coupling of 4-bromo-1-butene (I) with catecholborane (II) afforded the bromobutyl boronate (III). Subsequent exchange of (III) with alpha-pinanediol (IV) produced (V), which was regioselectively chlorinated to give (VI). Displacement of the chlorine atom of (VI) with lithium hexamethyldisilazide, followed by acid treatment furnished intermediate (VII).

该中间体在本合成路线中的序号：(VII)

Condensation of cyclopentanecarboxylic acid (VIII) with ethyl chloroformate in the presence of LDA afforded 1,1-cyclopentanedicarboxylic acid monoethyl ester (IX), which was coupled with phenethylamine (X) by means of TBTU to produce amide (XI). Ester hydrolysis of (XI) with NaOH gave carboxylic acid (XII), which was activated as the mixed anhydride (XIII) with isobutyl chloroformate, and then coupled to the chiral aminoboronate (VII), yielding diamide (XIV). Displacement of the bromine of (XIV) with NaN3, followed by hydrogenation of the resulting azide (XV) gave rise to amine (XVI). The chiral auxiliary of (XVI) was finally removed by treatment with phenylboronic acid.
