Abnormal reactions of 2-methoxy-4,9-dimethyl-1-nitroacridine with selenous acid and selenium(IV) oxide. Synthesis of 1H-selenopheno[2,3,4-k,l]acridine-1- one: A new seleno-containing ring system

experimental part, p. 209 - 214 (2011/04/15)
Unusual course of the reaction was revealed on the oxidation of functionally substituted acridine containing the activated methyl groups by well-known oxidants, such as selenous acid and selenium(IV) oxide. Treatment of 2-methoxy-4,9-dimethyl-1-nitroacridine (5) with an excess of H 2SeO3 in boiling ethanol gave a mixture of the normal reaction products, 2-methoxy-4-methyl-1-nitro-9-formylacridine (11) (isolated yield 29%) and 2-methoxy-4-methyl-1-nitroacridine-9-carboxylic acid (12) (36%), together with an abnormal product, 3-methoxy-5-methyl-1H-selenopheno[2,3,4-k,l] acridine-1-one (13) (21%), which is the first example of a new seleno-containing ring system. With the use of SeO2 the yield of selenolactone 13 was much lower.

, p. 1063 - 1066 (2007/10/03)
A facile enantioselective synthesis of the 2-aminoimidazole side-chain of dragmacidin D has been developed, which involved the regio- and stereoselective opening of the chiral epoxide 9 by a diindolylcuprate reagent, followed by further steps to give 5-substituted N-(1H-imidazol-2-yl)acetamide 2.
