Palonosetron hydrochloride was synthesized by reductive amination of (3,4-dihydronaphthalen-1-yl)methylamine hydrochloride with 3-quinuclidinone hydrochloride subsequent reduction to give N-((3,4-dihydronaphthalen-1-yl)methyl)-1-azabicyclo(2.2.2)octan-3-amine dihydrochloride,which was subjected to resolution,catalytic hydrogenation,and cyclization with triphosgene in 12% overall yield.
Catalytic activity assay with recombinant protein demonstrated that DnTR1 was able to reduce tropinone, 3-quinuclidinone hydrochloride, and 4-methylcyclohexanone using NADPH as coenzyme. Gene expression profiling by qRT-PCR revealed that the DnTR1 transcript was expressed in all three vegetative organs (leaves, stems and roots) of D. nobile with the highest expression level in roots.
A new synthesis of sabcomeline hydrochloride has been described: The hydrolysis of quinuclidine-3-carboxylic acid ethyl ester (I) with refluxing aqueous HCl gives the corresponding acid (II), which by reaction with thionyl chloride in refluxing dichloromethane yields the expected acyl chloride (III).
