report the development of the first enantioselective Dakin–West reaction, yielding α‐acetamido methylketones with up to 58 % ee with good yields. Two of the obtained products were recrystallized once to achieve up to 84 % ee. The employed methylimidazole‐containing oligopeptides catalyze both the acetylation of the azlactone intermediate and the terminal enantioselective decarboxylative protonation. We

Asymmetric transferhydrogenation of cyclic and acyclic α,β-unsaturatedketones catalysed by η6-p-cymene/ruthenium(II) and η5-pentamethylcyclopentadienyl/rhodium(III) complexes have been investigated. Cyclicα,β-unsaturatedketones appeared to be more suitable substrates for the synthesis of enantiomerically pure allylic alcohols than do acyclic α,β-unsaturatedketones. A proposed mechanism for the
环状和无环α的不对称转移氢化,β不饱和酮由η催化6 - p -cymene /钌(II)和η 5 -五甲基/铑(III)络合物进行了研究。环状α,β-不饱和酮似乎比无环α,β-不饱和酮更适合用于合成对映体纯的烯丙基醇。讨论了一种由α-甲苯磺酰氧基和卤素取代的苯乙酮形成4-苯基-[1,3]-二氧戊环-2-酮的机理。提出了进一步研究减少α-甲苯磺酰氧基苯乙酮范围和α-取代酮的动态动力学拆分的结果。

ability to inhibit VEGFR-2 kinase enzyme in vitro. All the tested compounds demonstrated highly potent dose-related VEGFR-2 inhibition with IC50 values in nanomolar range. Among these compounds, pyrrolo[2,3-d]pyrimidine derivatives carrying biaryl urea moieties (12d and 15c) exhibited IC50 values of 11.9 and 13.6 nM respectively. Additionally, most of the newly synthesized final compounds were tested on 60
血管内皮生长因子受体2(VEGFR-2)在癌症血管生成中起着至关重要的作用。在当前的研究中,根据已知II型VEGFR-2抑制剂的结构活性关系(SAR)研究,设计并合成了一系列新型的基于吡咯并[2,3- d ]嘧啶的化合物作为VEGFR-2抑制剂。 。评价了新合成的化合物在体外抑制VEGFR-2激酶的能力。所有测试的化合物均表现出高度有效的剂量相关的VEGFR-2抑制作用,IC 50值在纳摩尔范围内。在这些化合物中,带有联芳基尿素部分(12d和15c)的吡咯并[2,3- d ]嘧啶衍生物表现出IC50个值分别为11.9和13.6 nM。此外,大多数新合成的最终化合物已在60种人类癌细胞系中进行了测试。进行了将这些化合物对接成VEGFR-2的非活性构象,这显示了与FDA批准的VEGFR-2激酶抑制剂相当的结合模式。这些新发现的有效激酶抑制剂可被视为开发新的靶向抗癌剂的潜在候选药物。
