The invention generally relates to methods and compounds for treating proliferative disorders, viral infections, or both. In some embodiments, the invention provides an anticancer or antiviral compound including a substituted nitro phenoxy phenyl, a sulfonylurea, and an alkyl group. In some embodiments, the invention provides a method of treating a proliferative disorder or a viral infection including administering an anticancer or antiviral compound that binds to a thromboxane receptor, has preferential binding for either TPalpha (TPα) or TPbeta (TPβ) receptor subtype.

sulfone group can then be cleaved. In this paper we describe several methods for the effective desulfonylation of BT sulfones and have developed methodology for one-pot alkylation-desulfonylation sequences. As such, overall, a one-carbon homologation sequence can be achieved in a two-pot (four step) procedure and the two-carbon homologation in a two-pot (three step) procedure (three-pot; four step when
本文中,我们报告了使用β-羰基苯并噻唑(BT)砜中间体通过Mitsunobu反应将1°和2°醇有效地一碳和二碳同系化为它们相应的同系酯。一碳同系物方法使用标准的Mitsunobu C–S键形成,氧化和随后的烷基化,而二碳同系物使用较少见的CC碳键形成Mitsunobu反应。在后一种情况下,使用含β-BT砜的酯会降低p K a足以将底物用作基于碳的亲核试剂并传递同源的β-BT砜酯,然后可以裂解该多余的砜基。在本文中,我们描述了几种有效进行BT砜脱磺酰化的方法,并开发了用于一锅烷基化脱磺酰化序列的方法。因此,总的来说,可以通过两锅法(四步法)实现一碳同源序列,而通过两锅法(三步法)(三锅;在C-包括酸合成)。该方法学已被应用于多种功能(酯,甲硅烷基醚,苄基,杂芳基,酮,烯烃和炔烃),并且均能很好地耐受,从而提供了很好的总收率。
Rapid methylation of terminal acetylenes by the Stille coupling of methyl iodide with alkynyltributylstannanes: a general protocol potentially useful for the synthesis of short-lived 11CH3-labeled PET tracers with a 1-propynyl groupElectronic supplementary information (ESI) available: general experimental remarks and synthetic methods and characterization of tributylalkynylstannanes and the corresponding methylacetylenes. See http://www.rsc.org/suppdata/ob/b3/b311532a/
The Pd(0)-mediated rapidcoupling (trapping) reaction of methyliodide with an excess amount of alkynyltributylstannane has been developed with the aim to incorporate a short-lived (11)C-labeled methyl group into biologically active organic compounds with a 1-propynyl structural unit.
