Reaction of 5'-O-p-methoxytrityl-thymidine with 1, 1'-carbonyl-diimidazole gave the 3'-O-carbonylimidazolide, which was condensed in high yield with 3'-O-protected thymidine to give a dithymidine carbonate. In the same way, we obtained the protected trithymidine dicarbonate. After deprotection, we obtained quantatively the trithymidine dicarbonate.By the same stratagy, we completed the synthesis of dithymidine sulfite.It was shown that allyl can be used as a good protection group for hydroxyl of ribose in the synthesis of oligonucleotides consisting in some unstable nucleotide analogues.

我们在第一部分工作的基础上，以烯丙基作为3'-OH的保护基合成了保护的三胸苷碳酸酯以及二胸苷亚硫酸酯，用我们所得的脱保护条件进行了脱保护研究，得到了三胸苷碳酸酯以及二胸苷亚硫酸酯，并研究了它们合成中的一些化学问题，结果表明：烯丙基能很好地运用于这两类寡核苷酸类似物的合成中，其脱保护条件为中性，不会影响碳酸酯键及亚硫酸酯键。

Drug sensitive test and three-dimensional test220 strains of Pa were isolated from hospitalized patients between 2003 and 2007. K-B method was used to tested the susceptibility of 10 different antibiotics. IRPa was screened by testing the minimal inhibitory concentration of imipemem by using agar diluiion method.The susceptibility of these IRPa to the antibiotics was analysised.
