The base catalysed hydrolysis of the antibiotic verrucarin A (C27H34O9) yields three products: (1) verrucarol (C15H22O4), a new sesquiterpene which is probably bicyclic, (2) muconic acid (C6H6O4), a new sesquiterpene which is probably bicyclic, (2) muconic acid (C6H6O4; cis,cis or cis, trans) and (3) verrucarinolactone (C6H10O3), the δ-lactone of the hitherto unknown trans-α,δ-dihydroxy-β-methylvaleric
抗生素维鲁卡林A(C 27 H 34 O 9)的碱催化水解产生三种产物:(1)维鲁卡罗(C 15 H 22 O 4),一种可能是双环的新倍半萜,(2)粘康酸(C 6 H 6 O 4),一种新的倍半萜,可能是双环的;(2)粘康酸(C 6 H 6 O 4;顺式,顺式或顺式,反式)和(3)紫丁香内酯(C 6 H 10 O 3)),是迄今为止未知的反式α,δ-二羟基-β-甲基戊酸的δ-内酯。Verrucarinolactone的绝对构型由其与(R)-(+)-甲基琥珀酸的相关性推导。芦丁酸代表甲羟戊酸的新的天然异构体。
