The structure of grandiflorone, a new β-triketone
Abstract
The structure 5-hydroxy-2,2,6,6-tetramethyl-4-(β-phenylpropionyl)cyclohex-4-ene-1,3-dione (I) is suggested for grandiflorone, a new β-triketone, which occurs together with small amounts of leptospermone and flavesone in the essential oils of Leptospermum flavescens Sm. var. grandiflora(Lodd.) Benth. and two distinct morphological forms of L. lanigerum(Ait.) Sm.
