the synthesis of a novel class of compounds, 1,2-dihydrofuro[3,4-d]pyrimidines (15, 16, 18, 20) starting from dimethyl furan-3,4-dicarboxylate 6. Synthesis of these compounds consist of two basic parts: Formation of 4-(2-azido-2-oxoethyl)furan-3-carbonyl azide 11 by eight organic reactions and formation of final products by intramolecular cyclization after two selective Curtius rearrangements of acyl
我们描述了一类新的化合物的合成中,1,2-二氢呋喃并[3,4- d ]嘧啶(15,16,18,20)从二甲基呋喃-3,4-二羧酸二甲酯原料6。这些化合物的合成由两个基本部分组成:通过八种有机反应形成4-(2-叠氮基-2-氧代乙基)呋喃-3-羰基叠氮化物11和在两次选择性叠氮化物的Curtius重排后通过分子内环化形成最终产物11。
