  Facile Synthesis of 4-Alkyl (and Aryl)-2-aryl-6-diazo-4H- thieno[3,2-b]pyridine-5,7-diones

  摘要：

  Treatment of 3-{3-alkyl (and aryl)amino-5-arylthieno-2-yl}-2-diazo-3-oxopropanoates 8 with TMSOTf (3 equiv) in the presence of Et3N (6 equiv) in CH2Cl2 for 1 h at room temperature afforded 4-alkyl (and aryl)-2-aryl-6-diazo-4H-thieno[3,2-b]pyridine-5,7-diones 14 in excellent yields. On heating of 14 in the presence of a catalytic amount of Rh-2(CF3CF2CF2CO2)(4) in PhH for 4-10 h at reflux, corresponding ring contraction products, 4-alkyl (and aryl)-5,6-dihydro-4H-thieno[3,2-b]pyrrol-5-ones 16, were produced in good to excellent yields.

  A concise and direct synthetic strategy for the construction of 2-aryliminochromene skeleton by cascade three-component coupling reaction of arynes, N,S-keteneacetals, and DMF in good yields has been disclosed. The process demonstrates the first example of aryne chemistry combined with N,S-keteneacetals. Using this strategy, an expeditious synthesis of biologically important arylimino-2H-chromene-3-

• Catalyst-Controlled Straightforward Synthesis of Highly Substituted Pyrroles/Furans via Propargylation/Cycloisomerization of α-Oxoketene-N,S-acetals

  A facile and efficient InCl3 catalyzed one-pot synthesis of highly substituted pyrroles has been developed via a tandem propargylation/cycloisomerization reaction of α-oxoketene-N,S-acetals with propargyl alcohols. Notably, in the presence of Bronsted acid p-TSA·H2O, the reaction afforded the hydrolyzed product propargylated-1,3-dicarbonyl compounds, which upon treatment with Cs2CO3 underwent regioselective

  通过α-氧杂环丁烯-N，S-乙缩醛与炔丙醇的串联炔丙基化/环异构化反应，已经开发出一种简便高效的InCl 3催化一锅合成高取代的吡咯。值得注意的是，在布朗斯台德酸对-TSA·H 2 O的存在下，反应提供了水解产物炔丙基化的1，3-二羰基化合物，其在用Cs 2 CO 3处理后进行了区域选择性的分子内环化，从而提供了四取代的呋喃衍生物。
• Heterocyclization of functionalized heterocumulenes with C,N-, C,O-, and C,S-binucleophiles: X. 1-Chloroalkyl isocyanates in the synthesis of new 5-aroyldihydropyrimidines

  Reactions of 1-chlorobenzyl isocyanates with N,S-aroylketene acetals depending on the conditions provide either 5-aroyl-6-methylsulfanyl-3,4-dihyropyrimidin-2(1H)-ones or 5-aroyldihyropyrimidine-2,4(1H,3H)-diones. 1-Aryl-2,2,2-trifluoro-1-chloroethyl isocyanates in a similar condensation gave 5-aroyl-6-methylsulfanyl-2-trifluoromethyl-2,3-dihyropyrimidin-4(1H)-ones.
