结果表明控制次氯酸钙与1， 1-环丙烷二甲酰胺的摩尔比为5：1、次氯酸钙质量分数为20%、反应时间为16h时，收率达95.4%。

For developing an immunoassay for multiple residues of pyrethroid pesticides, the hapten N-2- carbanmoyl-(3"-phenoxyphenyl) methyl 3-(2"-Cldoro-3",3",3"-trifluoropropenyl)-2, 2-dimethylcyclopropane- carboxylate was synthesized from cyanohydrin and 3-(2"-Chloro-3",3",3- trifluoropropenyl)-2, 2-dimethylcyclopropanecarboxylic acid via hydrolysis and esterification. The synthesis of the hapten was foundation of preparaing anti- cyhalothrin polyclonal antibodies.

为了制备对单一拟除虫菊酯高特异性的抗体，以菊酸和氰醇为起始原料，通过水解、酯化反应合成了半抗原N-2-氨甲酰-(3-苯氧基苄基)甲基-3-(2-氯-3，3，3-三氟丙烯基)-2，2-二甲基环丙烷羧酸酯，为进一步制备抗三氟氰菊酯的特异性抗体奠定基础。

This paper reviews the recent progress in the synthesis of cyclopropane amino acids.

本文综述了合成环丙烷氨基酸类化合物的近期研究进展。

A previous study, which found that cyclopropane and chloroethane decreased the solubility of benzene in water, probably erred in its conclusion that these anesthetics interfered with the interaction of benzene and water.

那个发现环丙烷和氯乙烷降低苯在水中溶解度的既往研究，可能在这些麻醉剂干扰了苯和水的相互作用的结论方面有误。

METHODS: We measured the effect of various lidocaine infusionson the MAC of cyclopropane, halothane, isoflurane, and o-difluorobenzenein rats.

我们测定不同的利多卡因输注对于大鼠环丙烷、氟烷、异氟醚和邻二氟苯 MAC 的影响。

Consistent with previous work on 122 GABAA receptors, we found in Xenopus oocytes that 5 MAC cyclopropane enhanced the effect of GABA on 122 GABAA receptors by only 76%, and by a nearly identical enhancement in 132, and 632 receptors.

与先前在α1β2γ2 γ-氨基丁酸 A 受体所得到的相符，我们发现在爪蟾卵上，5倍的环丙烷最低肺泡有效浓度增加了γ-氨基丁酸在α1β2γ2 γ-氨基丁酸 A 受体上的作用仅76％，在α1β3γ2 γ-氨基丁酸 A 受体及α6β3γ2 γ-氨基丁酸 A 受体上的加强作用也几乎一致。

Chiral ligands mentioned above and their complexes with acetate copper were used as enantio-selective catalysts in asymmetric cyclopropanation reactions of diazoacetate and 1,1-diphenyl ethylene. Investigations indicate that all of them reveal certain optical-selective capability, but chiral C2-symmetric 2,6-bispyridine ligands show better catalytic capability than chiral asymmetric schifF-base ligands.

选择了2个手性2，6-吡啶双噁唑啉配体和6个手性不对称席夫碱配体与醋酸铜形成的配合物作为催化剂，对重氮乙酸乙酯与1，1-二苯乙烯不对称环加成进行催化反应，发现这8个催化剂对1，1-二苯乙烯的不对称环丙烷化反应都表现出了一定的光学活性诱导能力，手性2，6-吡啶双噁唑啉-铜类具有比手性Schiff碱-铜类更好的催化性能。

In the CsF promoted Strecker reactions of 2-aziridinesulfinimines, the sulfinyl group controlled the diastereoselective addition.

加成产物经氮杂环丙烷开环可合成所有构型的一系列α、β-二氨基酸和α、β-二氨基膦酸。

The result obtained was very promising. Meanwhile, [3+2]-cycloaddition of aziridines with nitriles was discovered by using Sc3 as catalyst.

与此同时，我们还发现了Sc3可以很好地催化腈与2-芳基氮杂环丙烷的[3+2]环加成反应，得到了二氢咪唑产物，产率中等到优秀。

In this reaction, DMSO may act as a Lewis base to activate the nucleophile, which facilitates the ring-opening reactions.

与此同时，我们还发现在DMSO中，无催化剂的中型条件下，硫，胺以及各类硅亲核试剂可以对氮杂环丙烷化合物开环。

Since historical times,England ,where the early inhabitants were Celts, has been conquered three times .

从有历史以来，英国，在此地早期居住的是凯尔特人，已经被征服了三次。
