Abstract

Convolvulaceae provide a rich source of tropane alkaloids, however, 2-substituted tropanes have been described for only few species of this taxon. In this note, 2,7-diesters such as ipvelutine [7β-acetoxy-2α-(tigloyloxy)tropane] isolated from the vegetative parts of the Australian Ipomoea velutina R. BR. are described as a new group of tropane diesters.

摘要

旋花科植物是托烷生物碱的丰富来源,然而,仅在该分类群的少数物种中发现了2-取代托烷。在本报告中,从澳大利亚绒叶甘薯(Ipomoea velutina R. BR.)营养部位分离得到的2,7-二酯类化合物,如绒叶碱[7β-乙酰氧基-2α-(惕各酰氧基)托烷],被描述为一类新的托烷二酯。
