June 2008 is Bibi's 2nd birthday.

六月二十二是比比两岁生日。

A series of novel chiral aminophosphine ligands with binaphthyl backbone and partially reduced binaphthyl backbone were synthesized from optically pure NOBIN and H〓-NOBIN respectively. The effects of binaphthyl backbone and substitutes at the phosphorous atom on Pd (0)-catalyzed allylation of racemic 1, 3-dipheylprop-2-en-1-yl acetate with dimethyl malonate were systematically investigated.

从NOBIN出发合成了一系列膦上含有不同取代基的氮膦配体MAPs以及含有被部分还原的联萘骨架的氮膦配体H〓-MAPs，将此两类配体运用于钯催化的乙酸1，3-二苯基烯丙基酯与丙二酸二甲酯的反应中，考查了膦上取代基和配体骨架对反应的影响。

Synergetic antifungal effects were observed in the combination of albicanyl caffeate or 3,4'-difluorostilbene and fluconazole, whereas additive antifungal effects were revealed when catechin or resveratrol combined with fluconazole.

当与氟康唑联合时，albicanyl caffeate和3，4'-二氟二苯乙烯显示出协同抗真菌活性，而儿茶素与白藜芦醇显示出相加的抗真菌活性。

The analysis of decomposition showed that the solid products were mainly dimethyl terephthalate and oligomer of PBT, whose end groups were carbomethoxy.

分解产物的分析结果表明：固相产物主要以单体对苯二甲酸二甲酯和端基为甲酯结构的PBT的低聚物为主。
