From phenylacetylphenylacetic acids to indoles: a simple new divergent synthesis of 6,11-dihydro-5H-benzo[a]carbazol-5,6-diones and 6,11-dihydro-5H-benzo[b]carbazol-6,11-diones
摘要:
The synthesis 6,11-dihydro-5H-benzo[a]carbazole-5,6-diones and 6,11-dihydro-5H-benzo[b]carbazole-6,11-diones from common starting materials, 1-(2'-nitrophenylacetyl)phenylacetic acids is described. (C) 2002 Elsevier Science Ltd. All rights reserved.

here a new, efficient generalsynthesis of o-acetylbenzoic acids by Heck palladium-catalyzed arylation of n-butyl vinyl ether with o-bromobenzoic acid esters and the use of these compounds as starting materials for the synthesis of 3-benzylideneisochroman-1,4-diones, which readily rearrange to 2-hydroxy-3-phenyl-1,4-naphthoquinones. The application of this strategy to the synthesis of indolo[2,3-b]naphthalene-6
我们在这里描述了一种新的,高效的,一般的合成方法,该方法通过Heck钯催化的正丁基乙烯基醚与邻溴代苯甲酸酯的芳基化反应来合成邻乙酰基苯甲酸,并将这些化合物用作合成3-苄叉基异色满1的原料,4-二酮,其容易重排为2-羟基-3-苯基-1,4-萘醌。还描述了该策略在吲哚[2,3 - b ]萘-6,11-二酮合成中的应用。
