In accordance with reported references, 8-methyl-8,14-cycloberbine was derived from berberinephenolbetaine. On acidic treatment the 8-methyl-8,14-cycloberbines were converted easily to the compounds $1{sim}7$ in good yields. We developed a novel method for a synthesis of the C8-N bond adduct compounds 8 and 9 from 8-methyl-8,14-cycloberbine by treatment with oxalyl chloride, and 1,3-dichloroaceton.
