Artest, 28, visited the Lakers' locker room during the NBA Finals and has spoken glowingly of Kobe Bryant in the past, but he told the Mason and Ireland Show on KSPN-AM (710) that it "looks like I'm going to be a King next year" before saying he would "never" take less money to play for a championship contender.

28岁的阿泰斯特在NBA总决赛拜访了湖人队的更衣室并畅谈了科比的过去，但是他在KSPN-AM (710)上的一个节目对Mason和Ireland表示我不会为了去一个有冠军竞力的球员而赚更的钱，之后说我下个赛季看起来还会在国王队。

There was a special panel discussion with Ambassadors from Montenegro, Tunisia, and Ireland.

这是一场很有意思的集体讨论，参会者是来自Montenegro， Tunisia， and Ireland的大使。

Second, using DBU as the base for enolization of propargylic esters of unsaturated acids 18e-k, we developed a tandem Ireland-Claisen rearrangement /isomerization reactions. It has been shown that the reaction sequence affords triene molecules 42a-b and 43a-b in moderated to high yields. Interestingly, with allyl hexa-3,5-dienoates 18i-j as the substrate, the rearranged products underwent further aromatization to give uniquely substituted benzyl acids 44a-b.

其次，以含有活泼质子的烯酸炔丙酯18e-k为底物，在DBU为烯醇化碱、TMSCl为硅试剂的条件下，底物18e-h发生了Ireland-Claisen重排/异构化串联反应，得到完全共轭的三烯类化合物42a-b及43a-b；而以己二烯酸炔丙基酯18i-j为底物时，重排/异构化后的产物进一步发生电环化等反应最终得到芳构化产物——取代苯甲酸类化合物44a-b。

We studied DBU-mediated Ireland-Claisen rearrangement. Using DBU as the base for enolization of allylic esters of unsaturated acids 9-16, we found a novel DBU-mediated tandem Ireland-Claisen rearrangement /isomerization reactions and established a consecutive Ireland-Claisen rearrangement /Cope rearrangement.

利用DBU作为烯醇化碱，对含有活泼质子的烯酸烯丙酯类化合物9-16的Ireland-Claisen重排进行了系统的研究，创建了一条新颖的DBU-促进的Ireland-Claisen重排/异构化串联反应及Ireland-Claisen重排/Cope重排的串联反应路线。

Based on the concepts of fragrance chemistry, under the guidance of molecules structure and odour relationships, we synthesized a list of potential odorants 46a-s, 47a-b, 48a-d and 49a-e by esterification, lactonization and reduction of the Ireland-Claisen rearranged products. Some of them were evaluated.

四、基于合成香料化学目前发展的现状，以香料的分子结构对香气影响的一些规律为指导，对所获得的部分Ireland-Claisen重排产物羧酸进行结构修饰，合成了系列潜香分子46a-s，47a-b，48a-d及49a-e，并进行了评香。

On the one hand, it's hard to understand that he isn't just at home in Ireland with Lavender and their daughters, owling back and forth with Dean, going about his normal, everyday business.

只是，我不明白他为什么不和Lavender和他们的女儿呆在Ireland，为什么要和Dean一起出来冒险呢，不好好的过他们的日子。

We studied Ireland-Claisen rearrangement of propargylic esters of unsaturated acids.

三、研究了不饱和羧酸炔丙酯类化合物的Ireland-Claisen重排反应。

First, when operating the DABCO-catalyzed Ireland-Claisen rearrangement of propargylic acrylates 18b-d, we added dienophiles 40a-f in the reaction system to capture the rearranged allenes products respectively. The Diels-Alder adducts 41a-i were obtained with complete regioselectivity. Thus a novel tandem Ireland-Claisen rearrangement /Diels-Alder reaction process with propargylic acrylates has been developed.

首先在进行DABCO-催化的丙烯酸炔丙酯类化合物18b-d的Ireland-Claisen重排反应的同时，于反应体系中分别加入亲二烯体40a-f捕获重排得到的连二烯中间体，一步反应获得了单一区域选择性的Diels-Alder环加成产物41a-i，从而创建了一条新颖的丙烯酸炔丙酯类化合物的Ireland-Claisen重排与Diels-Alder环加成的串联反应路线。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
