mercaptoacetate in the presence of triethylamine results in the formation of 1,2-dihydrothieno[2,3-c]chromen-4-ones and diethyl 3,4-dithiadipate in high yields. Oxidation of the first compounds with nitrogen dioxide gave 1,2-dihydrothieno[2,3-c]chromen-3,4-diones which were converted into thieno[2,3-c]chromen-4-ones.
在三乙胺的存在下,2-三氟甲基色酮与巯基乙酸乙酯的氧化还原反应可高产率地形成1,2-二氢噻吩并[2,3 - c ]铬-4-酮和3,4-二硫代二乙酯二乙酯。用二氧化氮氧化第一化合物,得到1,2-二氢噻吩并[2,3- c ] chromen-3,4-二酮,将其转化为噻吩并[2,3 - c ] chromen-4-ones。

2-(trifluoromethyl)chromones react with cyanoacetamides in the presence of sodium ethoxide to produce 6-(2-hydroxyaryl)-4-(trifluoromethyl)-2-oxo-1,2-dihydropyridine-3-carbonitriles, their reactions with ethylcyanoacetate and diethyl malonate under the same conditions took an entirely different course and gave novel functionalized derivatives of 6H-benzo[c]chromen-6-one.
尽管2-(三氟甲基)色酮在乙醇钠存在下与氰基乙酰胺反应生成6-(2-羟基芳基)-4-(三氟甲基)-2-氧代-1,2-二氢吡啶-3-甲腈,但它们与乙基的反应在相同条件下,氰基乙酸酯和丙二酸二乙酯采用完全不同的过程,得到了6 H-苯并[ c ] chromen-6-one的新型官能化衍生物。

Abstract2-Polyfluoroalkylchromones react with aliphatic 1,2-diamines to give 2,3-dihydro-1H-1,4-diazepines. A similar reaction with 1,3-diaminopropane yieldsN,N′-trimethylenebis(2-hydroxyacetophenomines) as a result of scission of the original chromones.
