Abstract

770 G. С. Hoops, J. Park, GA Garcia, and LB Townsend Vol. 33 doublet for H-6 might be expected if N-7 was protonated. However, the signal for H-6 does not consistently appear as a doublet in the unmethylated or N-3-methylated analogs. The uv spectra (see Table 1) of these compounds are nearly identical to their corresponding unmethylated analogs. Methylation at Nl or O-alkylation to give the corresponding 4-methoxy analogs would be expected [12] to produce a ...
