The lithium salt of methyl tetronate adds to 3,4-dihydro-6,7-dimethoxy-2-methylisoquinolinium iodide and affords a mixture of three coupled products. Zinc chloride has been found to suppress formation of one of these isomers. These compounds may be thought of as precursors to a new class of C-nucleosides.
