Rm. Ede et al., NOVEL NOR-SESQUITERPENOIDS IN NEW-ZEALAND HONEYS .2. ISOLATION AND STRUCTURAL CHARACTERIZATION OF MELIRACEMOIC ACID, Tetrahedron letters, 34(42), 1993, pp. 6795-6798
Meliracemoic acid, a novel nor-sesquiterpenoid isolated from the honey
of the New Zealand native tree kamahi (Weinmannia racemosa), has been
shown to possess a substituted 2,5-methano-hexahydro-1,3-benzodioxola
ne skeleton. The structure was determined principally by 1D and 2D NMR
analysis of the corresponding methyl ester.
