合成路线1
该中间体在本合成路线中的序号:(III)The reaction of S-methylisothiourea (I) with Boc2O by means of NaHCO3 gives the N-Boc protected isothiourea (II), which is condensed with 1,4-butanediamine (III) in hot THF to yield the guanidine derivative (IV). The acylation of the amino group of (IV) with 3,4-dimethoxycinnamoyl chloride (V) with THF/DMF affords the corresponding amide (VI), which is deprotected with TFA to provide N-(4-guanidinobutyl)-3,4-dimethoxycinnamamide (VII). Finally, the guanidino group of (VII) is alkylated with 3-methyl-2-butenyl bromide (VIII) catalyzed by DMAP in THF to provide the target, caracasanamide.

合成路线3
该中间体在本合成路线中的序号:(I)The mono-Boc-protected diamine (II) was obtained by reaction of 1,4-diaminobutane (I) with Boc2O. Reductive alkylation of (II) to the benzylic amine (V) was carried out in a two-step procedure consisting in condensation of amine (II) with the formyl boronic ester (III) in the presence of molecular sieves, followed by reduction of the resultant imine (IV) with NaBH4. The N-Boc protecting group of (V) was then removed by acidic treatment, yielding diamine (VI). The title boronic acid was finally obtained by boronate ester exchange in (VI) with phenylboronic acid in a two-phase system.
