  New synthesis of N-substituted benz[g]isoquinoline-3,5,10(2H)-triones

  摘要：

  Various N-substituted benz[g]isoquinoline-3,5,10(2H)-triones 7 were prepared starting from vitamin K-3 (menadione) 9. The key steps involve substitution of a benzylic bromide by a primary amine and intramolecular condensation across the ester moiety of a (3-bromo-methyl -naphth-2-yl) acetate 8 followed by oxidation with cerium(IV) ammonium nitrate (CAN) and spontaneous dehydrogenation, resulting in the title compounds 7. A selection of the synthesised new compounds was tested in vitro against Mycobacterium tuberculosis. (c) 2007 Elsevier Ltd. All rights reserved.

  The synthesis of 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-dione hydrochlorides is reported starting from 1,4-dihydrobenz[g]isoquinoline-3(2H)-ones or ethyl (3-aminomethyl-1,4-dimethoxynaphth-2-yl)acetates. A third strategy relies on the synthesis of the title compounds via an N-protected 2-(3-bromomethyl-1,4-dimethoxynaphth-2-yl)ethylamine. The synthesized 1,2,3,4-tetrahydro-benz[g]isoquinoline-5,10-diones are a new class of quinones, which have not been reported yet. (C) 2008 Published by Elsevier Ltd.
