Novel domino reactions for diterpene synthesis
Bhar, Shanta S.,Ramana
, p. 8935 - 8937 (2004)
New types of concerted domino acylation-cycloalkylation/alkylation- cycloacylation reactions have been described. These processes promoted by methanesulfonic acid-phosphorus pentoxide and concentrated H2SO 4, respectively, provide efficient, elegant, and expeditious routes for biologically active naturally occurring diterpenoids, namely (±)-ferruginol (1), (±)-nimbidiol (2), (±)-nimbiol (3), (±)-totarol (4), and ar-abietatriene (5).

The present invention discloses (+/-)-ferruginol analogs represented by formulas (I) and (II), and a preparation method thereof, wherein a tricyclic diterpene analog (1) is used as a raw material, andesterification, acylation, oxidation, reduction, dehydroxylation, deprotection, dehydration, halogenation, demethylation and other reactions are performed to obtain the (+/-)-ferruginol analogs represented by the formulas (I) and (II). The invention further discloses a total synthesis method of (+/-)-ferruginol, wherein a compound (16b) as a raw material and a Grignard reagent are subjected to aGrignard reaction, and a dehydroxylation reaction and a demethylation reaction are performed to obtain the (+/-)-ferruginol. According to the present invention, the prepared (+/-)-ferruginol analogs represented by the formulas (I) and (II) have significant antibacterial activity and can be potentially used for the preparation of antibacterial drugs. The formulas (I) and (II) are defined in the specification.
