  Synthesis and biological evaluation of 1,1-Dichloro-2,3-diarylcyclopropanes as antitubulin and anti-breast cancer agents

  摘要：

  Z-1,1-Dichloro-2,3-diphenylcyclopropane (1) is an effective 'anti-breast cancer agent in rodents and in cell culture. We recently determined that 1 inhibits tubulin assembly in vitro. and causes microtubule loss in breast cancer cells, leading to accumulation in the G2/M portion of the cell cycle. Aryl ring-halogenated, methoxylated and benzyloxylated derivatives of 1, as well as its E-isomer and the dichlorocyclopropyl derivative of diethylstilbestrol (DES), were synthesized and tested for their ability to inhibit the assembly of tubulin into micro tubules. Including 1, 17 cyclopropyl compounds were tested. One (Z-1,1-dichloro-2-(4-methoxyphenyl)-3-phenylcyclopropane (12)) was found to be more active than 1. In addition, E-1,1-dichlorocyclopropylDES (17) was more potent than DES. The E-isomer of 1 (16) was inactive. The cytostatic activities of the compounds against MCF-7 and MDA-MB231 human breast cancer cells, and their abilities to perturb microtubules in MCF-7 cells were also evaluated. Z-Dichloro-2-(4-fluorophenyl)-3-phenylcyclo (5), Z-1,1-dichloro-2-(4-fluorophenyl)-3-(4-methoxyphenyl)cyclopropane (11), and Z-1,1-dichloro-2-(4-methoxyphenyl) -3-phenylcyclopropane (12) were more potent than 1 against the breast cancer cells.

• Carbonyl–Olefin Cross‐Metathesis Through a Visible‐Light‐Induced 1,3‐Diol Formation and Fragmentation Sequence

  cross‐metathesis is described. Photoinduced hole catalysis was used to promote the formation of 1,3‐diols from aldehydes and styrenes, which were then readily fragmented under acidic conditions to form the cross‐metathesis products. The use of 1,3‐diols as intermediates, rather than the energetically more demanding oxetanes, provides a new, orthogonal mechanistic strategy for carbonyl–olefin cross‐metathesis.

  描述了可见光介导的羰基烯烃交叉复分解方法。光诱导空穴催化用于促进醛和苯乙烯形成1,3-二醇，然后在酸性条件下容易裂解形成交叉复分解产物。使用1,3-二醇作为中间体，而不是对能量要求更高的氧杂环丁烷，为羰基烯烃交叉复分解提供了一种新的正交机理。此外，这种方法不需要任何金属，配体或添加剂，并为产品提供了高水平的E。 选择性。提供了一种机械原理，并得到了理论计算和实验的支持。此外，还介绍了一种新的基于a啶的光催化剂的实用合成方法，包括完整的表征。
