  Rhodium-catalyzed [2 + 2 + 2] cycloadditions, sulfonyl phthalide annulations and nitroalkene reactions have been employed for the synthesis of 56 quinone-based compounds. These were evaluated against Trypanosoma cruzi, the parasite that causes Chagas disease. The reactions described here are part of a program that aims to utilize modern, versatile and efficient synthetic methods for the one or two

  日期：2020.1.3

  The first examples of Rh-catalyzed [2 + 2 + 2] cycloadditions between diynes and benzoquinones are described. The method enables de novo and step-economical access to challenging naphthoquinones that are of relevance to lignan and type II polyketide synthesis. The value of the chemistry is demonstrated by a short total synthesis of justicidone.

• Synthesis of 3-[(N-carboalkoxy)ethylamino]-indazole-dione derivatives and their biological activities on human liver carbonyl reductase

  A series of indazole-dione derivatives were synthesized by the 1,3-dipolar cycloaddition reaction of appropriate substituted benzoquinones or naphthoquinones and N-carboalkoxyamino diazopropane derivatives. These compounds were evaluated for their effects on human carbonyl reductase. Several of the analogs were found to serve as substrates for carbonyl reductase with a wide range of catalytic efficiencies, while four analogs display inhibitory activities with IC50 values ranging from 3-5 mu M. Two of the inhibitors were studied in greater detail and were found to be noncompetitive inhibitors against both NADPH and menadione with K-I values ranging between 2 and 11 mu M. Computational studies suggest that conformation of the compounds may determine whether the indazole-diones bind productively to yield product or nonproductively to inhibit the enzyme.

• 2H-Isoindol-4,7-dione durch Addition von Azomethinyliden an 1,4-Benzochinone
  作者：Manfred Schubert-Zsilavecz、Werner Likussar、Dagmar Gusterhuber、Astrid Michelitsch

  DOI：10.1007/bf00809659

  日期：1991.5

  A new approach to the synthesis of 2H-isoindole-4,7-diones is described. Heating alpha-amino acids with carbonyl compounds generates azomethine ylides through the elimination of water and carbon dioxide. The ylides were captured by quinones forming 2H-isoindole-4,7-diones, 2,3,3a,7a-tetrahydro-1H-isoindole-4,7-diones and 2,3-dihydro-1H-pyrrolo[2,1-a]isoindole-6,9-diones. The structures were established on the basis of spectroscopy (NMR, mass).
