Both the protection and deprotective group methods for the amino-group on side chain of a new N-pivot lariat crown ether were studied comparatively.

研究了一种新的氮支套素冠醚侧链上氨基的保护和脱保护基方法，结果表明，由过量乙二胺与对甲苯磺酰氯反应得到的单保护乙二胺（N－对甲苯磺酰基乙二胺4a），经N－烷基化环化反应，然后在氢化铝锂存在下脱除保护基，即可制得最佳产率的N－（2－氨基已基）单氮杂－12－冠－4（1）。

In D3 gene with 5 site mutations. There exists individual variation in the COII gene, but this variation is less than that among other members of Myzomyia Series such as An. aconitus, An. jeyporiensis, etc. In addition, one haplotype different from both An. minimus A and C was found in these 3 genes studied.②The genetic distance between An. minimus A and An. minimus C is less than that among other members of Myzomyia Series. Molecular trees based on different genes and different methods show that An.

种系发生研究表明，微小按蚊复合体亲缘种A、C间的遗传距离远小于与之近缘的同系其它成员间的距离。2个分子标记3种方法构建的基因树显示，微小按蚊A、C的种系地位非常固定，不同地域来源、不同变异类型的微小按蚊始终在同一分"枝"上，与迈蚊系其它成员相比，呈现其相对稳固的单源性。
