Chemical modifications of (+)-allo-aromadendrane-10b,14-diol isolated from duguetia glabriuscula r. e. fries (r. e. fries) (annonaceae) and biological evaluation of some obtained derivatives

The sesquiterpene (+)-allo-aromadendrane-10b-14-diol 1 was the lead compound to the preparation of several derivatives in order to test their biological activity against A. salina, C. sphaerospermum, E. coli and S. aureus. In this way the monoalcohols (+)-viridiflorol 4, 9 and 11 were synthesized from 1 together with the acetal 6, the ketal 7, and the ketone 8. The oxirane 3 and nitrile 5 were also prepared using as an intermediate the tosylate derivative 2.
