帮忙翻译一下，地道的英语是最好的。修改着急中！再次先行谢过！ Mikami et al于2004年报道了以天然乳酸酯为原料对1-烷基咪唑进行烷基化来制备CILs，这些CILs具有较低熔点等优点。Tao等在2005年报道直接对手性а-氨基酸或а-氨基酸酯进行酸化制备了一系列的CILs。2003年Bao等报道了利用天然手性胺和 氨基酸直接合成带有手性中心的烷基咪唑，再烷基化制备CILs，该方法具有原料易得，化学稳定性好，步骤简单和低熔点等优点。使得该CILs在不对称合成中的应用成为可能。Levillain等采用廉价的-氨基-1-丁醇与二硫代的2-甲基丙酸酯进行缩合制备噻唑啉，然后通过烷基化制备了一系列新型CILs。该CILs具有好的热稳定性，在碱性条件下也是稳定的，甚至酸性条件下也有一定的稳定性。Ge′nisson等在2005年又报道了从手性胺出发。合成了一系列2-烷基取代的咪唑盐CILs和相应的二氢化的咪唑盐CILs，该类型CILs具有很低的熔点，在不对称合成中具有潜在的应用价值。2005年，Baro等利用手性烷基化试剂对Ⅳ-甲基咪唑进行烷基化，合成了一种具有液晶性质的CILs。 |

| Mikami et al in 2004 reported to the natural lactic acid ester as raw materials for 1 - Alkylimidazolium prepared to carry out alkylation CILs, which has a low melting point CILs advantages. Tao in 2005, and other opponents of direct reports а-а-amino acids or amino acid ester prepared to carry out a series of CILs. Bao reported in 2003, such as the use of natural chiral amines and amino acids with the direct synthesis of chiral center Alkylimidazolium, alkylation Preparation CILs, the method is easy to get raw materials, chemical stability, low melting point and simple steps, such as Advantages. CILs made in the Asymmetric Synthesis possible. Levillain such as the use of low-cost - amino -1 - butanol and two of the S 2 - C methyl ester preparation for condensation thiazoline, and then through the alkylation prepared a series of new CILs. The CILs have good thermal stability in alkaline conditions is stable, even under the acidic conditions of a certain degree of stability. Ge'nisson, such as in 2005 and reported from the hands of the starting amine. A series of 2 - alkyl substituted imidazole salt CILs and the corresponding dihydro the imidazole salt CILs, the type of CILs have a very low melting point, in asymmetric synthesis potential value. In 2005, Baro, such as the use of chiral reagents for the alkylation Ⅳ - methylimidazole for alkylation, with a synthetic liquid nature of the CILs. |

不好意思，早上时间有限，只翻译了一部分，如果需要中午继续翻译，我的QQ号是：44748067 昵称：linger凌凌 Preparation CILs used natural lactic acid ester as stuff to alkylation 1- Alkylimidazolium, reported by Mikami et al in 2004. These CILs owns advantages of lower melting Point,etc. A series of CILs was made by direct acidification chiralа-amino acids orа-amino acid ester reported in 2005 by Tao, etc. |

Alkylimidazolium with chiral center was directly synthesized using natural chiral amines and amino acids, then alkylation preparation CILs was reported in 2003 by Bao,etc. The method owns adwantages of raw materials is easy to get, chemical stability is good, steps are simple and melting Point is low,etc. Application of the CILs in asymmetric synthesis becomes possible. Cheap amino-1–butanol and two sulpho-2-methyl propionate were adopted to condensation prepare thiazoline,then a series of new type CILs were prepared with alkylation by Levillain etc. The CILs own good thermal Stability, stable under alkaline conditions, and even own some stability under acidic conditions also. Synthesis a series of 2-alkyl substitutive imidazole salt CILs and corresponding two hydrogenation imidazole salt CILs starting from chiral amines was reported in 2005 by Ge′nisson, etc. The type of CILs owns very low melting Point, snd owns potential application value in asymmetric Synthesis. In 2005, alkylation Ⅳ-methylimidazole was carried out with chiral alkylation reagent and a kind of CILs with nature of liquid crystal was synthesized by Baro, etc No thanks. 顺便祝你新年快乐！春节快乐！ |

希望能翻译的再地道一点！谢谢 Deng等在2005年分别以咪唑、吡啶及PPh，和磺酸内酯为原料合成了系列的带有磺酰氯的FACLs，该离子液体为强酸性物质，可以作为许多酸催化反应的介质或催化剂。Varma等在2005年报道了利用微波促进，无溶剂法制备以二烷基咪唑盐为阳离子，InCl4-为阴离子的FAILs，该法具有操作简便，环境友好等优点。他们利用该离子液体为催化剂。在微波促进下对醇进行四氢吡喃化来保护羟基，取得了很好的结果。对于具有Bronsed酸性的FALLs一般都需在普通离子液体中引入质子源。Cole等在2002年首次报道了具有较强Bronsed酸性的FAILs的合成。 近年来，作为环境友好型绿色溶剂的离子液体，已受到世界各国的广泛关注，它在不同的领域都有潜在的应用价值。人们已经开发出多种手性离子液体，它们的应用研究也已经起步。除了开发特殊的功能和应用，降低手性离子液体的成本也是其发展的关键。合成时需要优先考虑的是手性源的选择，使用天然手性源作为起始原料将是获得手性离子液体的发展方向。Lewis酸性的离子液体尤其是A1C13类离子液体的发展较早，应用也较广；相比之下，Bronsted酸性离子液体的合成才刚刚起步。从已有研究可以看到，要开发适于工业应用的酸性离子液体，应充分发挥酸性离子液体类似固体酸和液体酸的优势，还需要进一步提高Bronsted酸性离子液体的酸强度；并发展兼具Lewis和Bronsted酸性的离子液体的合成方法。设计出具有独特物理化学性质的功能化离子液体来适应各种特殊需要将是功能化离子液体未来发展的方向。 |
