✦ Synopsis
The electrochemical oxidation of dierent methoxynaphthalenes to aord the corresponding 5,8-dihydroxy-1,4-naphthoquinones has been examined. This method constitutes a new alternative and ecient route for the synthesis of the 5,8-dihydroxy-1,4-naphthoquinone nucleus.

## Abstract The reaction of 1‐(2‐aminophenyl)pyrrole with aromatic or heteroaromatic aldehydes in ethanol and catalytic amounts of acetic acid leads to 4,5‐dihydropyrrolo[1,2‐__a__]quinoxalines in high yields. When aliphatic aldehydes were used under the same conditions, a slow oxidation to the cor
