All four isomers of the spermine alkaloid kukoamine were unambiguously prepared through diacylation with O,O′-dibenzylcaffeyl chloride of suitably protected (benzyl and/or trityl groups) spermine derivatives, assembled on solid and/or in liquid phase using β-alanine and γ-aminobutyric acid, followed by simultaneous N- and O- deprotection and double bond reduction using catalytic hydrogenation.
通过与适当保护的(苄基和/或三苯甲基)精胺的O, O'-二苄基咖啡酰氯二酰化,明确制备精胺生物碱古柯胺的所有四个异构体,并使用β-丙氨酸和γ将其固相和/或液相组装-氨基丁酸,然后同时进行N-和O-脱保护和使用催化氢化的双键还原。
