A series of new 2,3-diamino-4-pyrimidinones and 3-amino-2-hydrazino-4-pyrimidinones were synthesized by the reactions of β-ketoesters with amino or diaminoguanidines.
Synthesis of thiophenecarboxamides, thieno[3,4- c ]pyridin-4(5 H )-ones and thieno[3,4- d ]pyrimidin-4(3 H )-ones and preliminary evaluation as inhibitors of poly(ADP-ribose)polymerase (PARP)

Treatment of 3-cyanothiophene with potassium nitrate and concentrated sulphuric acid gave 5-nitrothiophene-3-carboxamide. 4-Nitrothiophene-2-carboxamide and 5-nitrothiophene-2-carboxamide were formed similarly from 2-cyanothiophene. Reduction with tin(II) chloride gave the corresponding aminothiophenecarboxamide salts which were isolated via their N-Cbz derivatives. Lithiation of 3,4-dibromothiophene at
A direction controlled Dieckmann type cyclization was performed on treatment of the half-thiol diesters(1) with base to give exclusively the β-keto esters (2.

an-3-ones are generally more enolized (40–74%) than the 2-ethoxycarbonylthiolan-3-ones (6–34%), and both series of compounds generally are less enolized than six-membered ring analogues. The extent of enolization of the title compounds is highly influenced by the nature and position of the ring-substitutents. Provable differencies in population of diastereomeric ketone forms related to the same, common
已经合成了一系列的2-和4-乙氧基羰基噻喃-3-酮,并通过1 H NMR和IR光谱进行了研究。在四氯甲烷溶液中互变异构平衡的条件下,与2-乙氧基羰基噻喃-3-酮(6-34%)相比,4-乙氧基羰基噻喃-3-酮通常被更烯化(40–74%),并且这两个系列的化合物通常都更少。比六元环类似物烯醇化。标题化合物的烯醇化程度高度受环取代基的性质和位置影响。根据立体化学鉴定,讨论了与相同,常见的烯醇形式有关的非对映体酮形式的可证明的差异。
