氯胺酮

One-pot reactions of 4 with isocyanates, triphenyl phosphine, hexachloroethane and triethylamine produced 2-anilino-5-arylidene-1-aryl-4,5-dihydroimidazo[1,2-b]-1',2',4'-triazol-4-ones 6 (or 7) in good yields.

而后用4与芳基异氰酸酯、三苯基膦、六氯乙烷和三乙胺"一锅"反应，得到4，5-二氢咪唑并[1，2-b]-1'，2'，4'-三唑-4-酮衍生物6或7。

Five quinazolinone compounds, such as 6-X-4(3H)-quinazoinone ( X=NO2,Cl,Br J) and 1 -furfuryl-6-sulfarnide-7-chloro-4( 1 H)-quinazolinone(5),were synthesized by reaction of anthranilic acids with formamide accompanied by titrating with phosphoryl chloride.

用改进后的 Niementowski反应，可使反应温度由原来的 175℃以上降至 90习5℃，甚至能在冰浴条件下制备出化合物 l－（吱哺－2－甲基）－6－磺酚胺基－7－氯什 IH）－喳哩晰酮。

Subsequently,enol methylation of P in basic condition completed the synthesis of malyngamide O.Applied this route to the synthesis of malyngamides Q and R,the chiral unsaturated acid was connected with the vinyl chloride part by amidation,then the resulting product was converted into the corresponding aldehyde,followed by aldol condensation of the aldehyde with the chlorotitanium enolate of pyrrolidone to complete the skeleton of malyngamides Q and R,then the synthesis of them was completed via enol methylation in acid condition.

该合成路线拓展应用到malyngamides Q和R的合成时，首先用酰胺键将手性不饱和脂肪酸和烯氯片段连接，再转化成相应的醛，与乙酰基吡咯酮进行TiCl_4催化的aldol反应即得到malyngamides Q和R的骨架结构，再经过酸催化的烯醇甲基化反应完成了Q和R的全合成。

Most of fluorenyl cardo polyimides exhibited excellent solubility in common organic solvents such as m-cresol,chloroform(CHCl_3), tetrahydrofuran,N-methyl-2-pyrrolidinone,N,N-dimethylacetamideetc and intrinsic viscosity in N,N-dimethylacetamideranged from 0.31-1.00dL/g.

大部分芴基Cardo型聚酰亚胺可以溶解在间甲酚，氯仿(CHCl_3)，四氢呋喃，N—甲基吡咯烷酮，N，N—二甲基乙酰胺等有机溶剂内，在DMAc内的特性粘度范围为0.31～1.00dL/g。

Fluoroalkyl acetic acids were converted to their corresponding carbonyl chlorides, and the latter reacted with o-aminpbenzyl aldehyde and ammonia gas to give 3-(1-imino-fluoroalkyl)-1H-quinolin-2-ones in moderate yields.

将2-氟烷基乙酸转化成相应酰氯，后者与邻氨基苯甲醛在通氨气条件下以较高产率转化为相应的3-（1-亚胺基-氟烷基）-1H-喹啉-2-酮。

Acetone, cyclohexanone, formaldehyde and ethylene diamine were adopted to synthetise HLZ corrosion inhibitor by means of Mannich reaction.Then LZ-620 salts corrosion inhibitor was synthetised on HLZ condensating chloroacetic acid.

针对盐类腐蚀采用丙酮、环酮A、甲醛、乙二胺通过曼尼希反应生成缓蚀剂后再与氯乙酸缩合生成盐类缓蚀剂(LZ-620)。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
