    A new example of 1α-hydroxylation of drimanic terpenes through combined microbial and chemical processes
    (2001) Aranda, G; Moreno, L; Cortés, M; Prangé, T; Maurs, M; Azerad, R
    Among various filamentous fungi, Aspergillus niger ATCC 9142 was the most efficient strain to convert confertifolin in high yield into its 3 beta -hydroxy derivative, which was then chemically converted to 1 alpha -hydroxy-, 1 alpha ,11 alpha -dihydroxy- and 1 alpha -acetoxy-11 alpha -hydroxyconfertifolin, new compounds structurally related to bioactive natural products isolated from plants or marine sponges.

    Microbiologically-assisted hemisynthesis of 1α-hydroxydrimenol
    (2001) Aranda, G; Cortés, M; Maurs, M; Azerad, R
    The hemisynthesis of 1 alpha -hydroxydrimenol has been selected to illustrate a synthetic route involving an initial microbial 3 beta -hydroxylation of a drimenol derivative followed by a functionalization transfer to position 1 alpha, thus generating a new potentially bioactive hydroxylated terpenic compound, Several methods have been investigated for the protection and the regeneration of the 7,8-double bond of drimenyl derivatives.
