合成路线1
该中间体在本合成路线中的序号：(IV)The oxidation of tricyclo[3.3.1.03,7]nonane-3-carboxylic acid methyl ester (I) with CrO3 in acetic anhydride/acetic acid gives a mixture of the 9-oxo and 6-oxo isomers (II), which is condensed with 5,6-diamino-1,3-dipropylpyrimidine-2,4(1H,3H)-dione (III) by means of LiOH, and after HPLC separation yields the 9-oxo isomer (IV) of the condensation product. The cyclization of (IV) by means of Ca(OH)2 affords the 1,3-dipropylxanthine derivative (V), which is finally reduced with LiBH4 to a mixture of isomers that is separated by HPLC yielding finally metabolite M1.
