Synthesis of 1-substituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones
1,2-Disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones are prepared for the first time through an activated Pictet-Spengler reaction of the corresponding imines of 2-(1,4-dimethoxynaphth-2-yl)ethylamine in the presence of an acyl chloride and AlCl3 followed by an oxidation with silver(II) oxide in nitric acid. Depending on the reaction conditions the N-trichloroacetyl protecting group could be cleaved off, converted to an N-methoxycarbonyl group or transformed to an N-(2-oxoacetamide) moiety. The synthesized 1,2-disubstituted 1,2,3,4-tetrahydrobenz[g]isoquinoline-5,10-diones constitute a new class of quinones, which has not been reported yet.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 17557-76-5, you can contact me at any time and look forward to more communication. Quality Control of 4,4′-Diamino-[1,1′-biphenyl]-2,2′-dicarboxylic acid.
