Complete NMR assignment of (+)‐10β,14‐dihydroxy‐allo‐aromadendrane

Abstract

The assignment of 1 H and 13 C NMR of the sesquiterpene (+)-10b,14-dihydroxy-allo-aromadendrane by means of two-dimensional NMR is reported.

A new sesquiterpene and other terpenoid constituents of Chisocheton penduliflorus

“…The unsymmetrical oxymethylene protons at position 14 were observed as a pair of doublets (J = 10.9 Hz) at 3.29 and 3.42. A NOESY experiment and comparison of these spectral data with reported values (San Feliciano et al, 1989;Vizzotto et al, 2003) helped identify compound 2 as allo-aromadendrane-10 , 14-diol.…”

Natural sesquiterpenoids

“…362 The complete NMR assignment of (+)-10␤,14-dihydroxy-allo-aromadendrane has been reported. 363 The chemistry of ledene and isoledene has been investigated. 364 (+)-Aromadendrane has been used as starting material in the synthesis of chiral methyl-branched linear pheromones.…”

“…Compound 1 is a natural product isolated from Pulicaria paludosa [ 1 ] and Duguetia glabriuscula [ 2 ]. Investigations concerning chemical modification [ 3 ], microbial transformation [ 4 ], electrolysis [ 5 ] and NMR assignments [ 6 ] of this molecule have demonstrated a great reaction versatility leading to unique carbon frameworks.…”
