The reported organocatalyst for asymmetric Michael additions include proline and its derivatives, chiral imidazolidinone derivatives, chiral urea, cinchona alkaloids and so on.

目前报道的催化Michael加成反应的有机催化剂主要有脯氨酸及其衍生物、手性咪唑啉酮、手性脲、金鸡纳碱衍生物等。

Nsted acids, chiral primary amines, cinchona alkaloids, etc.

nsted酸、手性伯胺、金鸡纳碱衍生物等。

So the ester type cinchona alkaloid derivatives should be the preferable catalysts for the IFB reaction withβ-phenyl substituted bromoketones as substrate.

由此可知，这类以酯键形成的金鸡纳生物碱衍生物适于催化β-苯取代溴乙酰甲酸乙酯为底物的IFB反应。

I am not sure that I ever heard the sound of cock-crowing from my clearing, and I thought that it might be worth the while to keep a cockerel for his music merely, as a singing bird. The note of this once wild Indian pheasant is certainly the most remarkable of any bird's, and if they could be naturalized without being domesticated, it would soon become the most famous sound in our woods, surpassing the clangor of the goose and the hooting of the owl; and then imagine the cackling of the hens to fill the pauses when their lords' clarions rested!

我不清楚在林中空地上，我听过金鸡报晓没有，我觉得养一只小公鸡很有道理，只是把它当作鸣禽看待，为了听它的音乐公鸡从前是印第安野鸡，它的音乐确是所有禽帼之中最了不起的，如果能不把它们变为家禽而加以驯化的话，它的音乐可以立刻成为我们的森林中最著名的音乐，胜过鹅的叫声，猫头鹰的嚎哭；然后，你再想想老母鸡，在她们的夫君停下了号角声之后，她们的噪聒填满了停顿的时刻！

In this season, lots of flowers are just marvelous...like Cleome, Lavender, Sunflower, Cosmos and Coreopsis auriculata."Nana" are blooming...

The extraction technology of yellow pigments in Coreopsis basalis was studied by use of single factor test and L_(16(4~5) orthogonal experiment design method in this paper.

通过单因素和L16(45)正交实验对金鸡菊花中黄色素的提取工艺进行了研究，获得提取最佳工艺条件为：pH值为3、体积分数65%的乙醇为浸提剂，按料液比1∶12投料，在50℃下浸提5h

Any of numerous plants of the genus Coreopsis having a profusion of showy usually yellow daisylike flowers over long periods; North and South America.
