中文摘要Oxidation of pseudaconine 8, a norditerpenoid alkaloid, with HIO4 led to a series of novel interesting products, depending greatly on reaction medium and work-up conditions, Treatment of 8 in MeOH-H2O (1:1) with NalO(4) gave compounds 10 and 11, but compound 12 was obtained quantitatively when the final reaction solution was alkalized with cone. NH4OH. The imine 12 was also obtained in 100% yield by treating 8 in 5% HCl solution with NaIO4 followed by alkalizing the reaction products to pH >9 with cone. NH,OH. When the work up pH was 7-8, only N,O-mixed acetal-ketal 13 was formed in 96% yield, which was converted quantitatively to 12 by further alkalizing, When the reaction mixture was alkalized to pH 7-8 with Na,CO,, a hemiacetalketal 14 was afforded quantitatively, which was converted to 15 in 87% yield by further treatment with Na2CO3 or 5% NaOH metbanol. Compound 15 could be concerted back to 14 by treatment with 10% HCl solution. Acetylation of the imine 12 gave the compounds 16 and 17 in 15% and 19% yields, respectively, All of the new compounds were isolated and fully characterized.
