  摘要：

  Aldoximes and ketoximes possessing gamma- or delta-alkenyl substituents undergo thermal conversion to 5- and 6- membered cyclic nitrones via a 1,3-azaprotio cyclotransfer, a 2n + 2-sigma + 2-pi concerted process, rather than a Michael addition. The reactions can be performed as a tandem nitrone formation-cycloaddition sequence or, if required, the intermediate nitrones can be isolated. The cycloadditions usually proceed via an exo-transition state and show both regio- and diastereofacial-specificity. Preliminary attempts at chiral induction via a menthyl auxiliary are reported.

  Synthesis and structure–activity relationship studies of novel tubulysin U analogues – effect on cytotoxicity of structural variations in the tubuvaline fragment

  摘要：

  Tubulysins是一种细胞毒性天然产物，具有有前景的抗癌特性，最初从粘细菌培养物中分离出来。在结构上，Tubulysins是四肽，包含三个不寻常的（Mep、Tuv和Tup）和一个蛋白质原生的氨基酸（Ile）。在这里，我们描述了新型Tubulysin U和V类似物的合成及其构效关系研究，这些类似物在中央Tuv片段上有所变化，该片段对于Tubulysins的效力和细胞毒性至关重要，但在先前的研究中很少被修改。具体而言，我们用其他结构相关的基团替代了天然的异丙基和乙酰氧基功能。总的来说，与天然Tubulysin U相比，新的类似物显示出较低的效力。然而，其中一个合成类似物（1f）具有MOM功能替代乙酰基，在HT-29细胞系上显示出22 nM的IC50，与Tubulysin U（3.8 nM）显示的IC50相当。此外，本文报道的合成方法被发现足够灵活，可以提供不同核心修饰的Tubulysin类似物，因此可以被视为产生新型Tubulysins类似物的可扩展和便捷策略。
