A versatile synthetic route to pterosins, sesquiterpenoid indanones present in bracken, Pteridiumaquilinum, has been developed. The route is exemplified by the synthesis of (2S,3S)-pterosin C by Friedel–Crafts bisacylation of the methyl ether of 2-(2,6-dimethylphenyl)ethanol with methylmalonyl chloride. Demethylation of the resulting 1,3-indandione and reduction with zinc and acetic acid in the presence of acetic anhydride and sodium acetate afforded a mixture of racemic cis and trans isomers of pterosin C diacetate, which was hydrolysed to the corresponding pterosins. Separation and resolution via the S-(+)-α-phenylbutyric esters gave (2S,3S)-pterosin C and (2R,3R)-pterosin C. Other pterosins were prepared as racemates from the 1,3-indandione.

Vinyl Derivatives

An efficient synthetic route for the novel bis-imdizo[1,2-a]pyridine-3-yl)methane (2a-k) derivatives have been developed using acetic acid and two drops of trifluoroacetic acid at 40-45oC, resulting in 60-72% yields. An attempt to synthesize bis(Imidazo[1,2-a]pyridin-3-yl)methyl chloride derivatives by the reaction between two moles of imidazo[1,2-a]pyridine, one mole of chloroacetaldehyde in acetic acid, and two drops of trifluoroacetic acid was not successful, instead underwent dehydrohalogenation to yield vinyl derivatives (4a-d).
