Chemistry &Biodiversity, EarlyView.ABSTRACT Chemical investigation of Disynaphia filifolia (Hassl.) R.M. King & H. Rob. (Asteraceae) led to the isolation of eight compounds, with tremetone being the major metabolite recovered. Tremetone has been suggested as the toxic compound in Ageratina altissima and Isocoma pluriflora, two species of the Asteraceae family. Although D.

Synthesis of glycosyl ferulate derivatives by amine-promoted glycosylation with regioselective hydrolysis using Novozym 435 and evaluation of their antioxidant properties [PDF]
, 2012 Various glycosyl ferulates were efficiently synthesized from 2,4,6-tetra-O-acetyl-α-d-glucopyranosyl bromide (TAGB) with amine by amine-promoted glycosylation without using heavy metal. The resulted acetylated glycosyl ferulates with acetoxyl groups at C-
