Nitrierungsprodukte von Antazolin und Bamipin und deren Meisenheimer Verbindungen mit Aceton und Basen

Nitro Products of Antazoline and Bamipine and Their Meisenheimer Compounds with Acetone and Bases Under the conditions of the Vitali-Morin reaction, antazoline and bamipine are nitrated to yield 17 nitro compounds, namely 1a/2b, 1b/2d, 1c, 1d/2e, 1e, 1f, 1g/2g, 2a, 2c, 2f, 2h–2n . Of these 1b/2d, 1c, 1e–1g/2g, 2a, 2c, 2h–2l produce coloured products when treated with bases in acetone. The coloured products 3a/b, 4a/b, 5a/b and 7 are Meisenheimer cyclohexadienate and propenide salts.
