Imatinib, a BCR-ABL tyrosine kinase inhibitor, is able to induce a complete cytogenetic response in more than 85% of patients with CML. However, the researchers note that patients with a complete cytogenic response tend to relapse when imatinib is discontinued, and less than 10% of patients achieve a molecular remission, defined by an undetectable residual disease using real-time quantitative–polymerase chain reaction.

Imatinib是一种BCR-ABL酪胺酸激酶抑制物，可以在85%以上的CML病患诱导完整的细胞生成反应；不过，研究者指出，完整细胞生成反应的病患倾向在停用imatinib时复发，不到10%的病患达到分子生物学上的缓解，其定义为以即时定量聚合酶连锁反应侦测不出残余疾病。

The first asymmetric synthesis of trans-β-hydroxy-γ-butyrolactones:-(3R, 4R, 5S)-4-(1-acetoxy-isopropyl)-3-hydroxy-butyrolactone 65a was achieved starting from isobutylaldehyde through nine steps. The key steps involve the construction of three chiral carbon centers by the Sharpless's asymmetric epoxidation and Substrate directable chemical reaction.

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.
