(Z)-2-メチル-2-ブテン酸[(1S,2R,7aR)-ヘキサヒドロ-2β-ヒドロキシ-1H-ピロリザイン-1β-イル]メチル 化学特性,用途語,生産方法
説明
A pyrrolizidine alkaloid, macrophylline has been isolated from Senecio amphibolus
and S. macrophylla MB. It forms a low melting solid which has not yet been
obtained in a crystalline form. The base is dextrorotatory having a specific rotation
of [α]
20D + 34.52° (c 1.68, EtOH). When hydrolyzed with dilute acids the base
furnishes macronecine and angelic acid. It has been characterized as the crystalline
bitartrate which melts at 162-4°C.
