—B are provided, wherein A is THIQ or a substituted derivative thereof and B is an aryl, cycloalkylaryl, or cycloalkyl group, wherein A and B are linked to each other by an alkyl or substituted alkyl chain. The compounds are useful as selective ligands (agonists or antagonists) of central nervous system receptors, and in particular of the seratonin receptors. The compounds or their salts can be formulated into pharmaceutical in need thereof by any route of administration suitable for a desired treatment protocol and especially for the treatment of psychiatric disorders.
The highly diastereoselective synthesis of perfluoroalkyl-containing pyrano[3,4-c]pyrroles has been accomplished via a cascade process involving Michael addition, Passerini-type reaction, Mumm rearrangement and an oxo-Diels–Alder reaction. This domino transformation of isocyanides, methyl perfluoroalk-2-ynoates and 3-aroyl (or heteroyl) acrylic acids proceeded smoothly at room temperature and led to
含全氟烷基的吡喃并[3,4- c ]吡咯的高度非对映选择性合成是通过级联过程完成的,该过程涉及迈克尔加成,Passerini型反应,Mumm重排和羰基-狄尔斯-阿尔德反应。异氰酸酯,全氟烷-2-甲基丙烯酸甲酯和3-芳酰基(或杂芳基)丙烯酸的多米诺骨转化在室温下平稳进行,并导致形成具有高官能团相容性的高非对映选择性目标化合物,并具有良好的产率。
Structures and Reactivities of 1-Oxo-cycloalkan-2-ylideneacetic Acids. A 1H NMR, Modelling and Photochemical Study
tendency to form tricyclic lactones with increasing size of the aliphatic ring. A theoretical structural analysis of the E and Z isomers, the tricyclic lactones and some of the hypothetical intermediates of the reaction with hydrazine suggests the size of the aliphatic ring and the associated flexibility to be crucial in modulating the ability of these compounds to form tricyclic products.
在脂肪族环的大小和缩合的不饱和环的性质上不同的四种1-氧代-环烷烃基-2-亚烷基乙酸对肼具有不同的反应性,仅在一种情况下导致所需的三环吡啶并哒嗪酮。观察到的行为差异不能归因于四种酸的环外双键的不同构型:1 H NMR实验结合UV光解表明,所有化合物均以E形式制备,并且在不存在E的情况下稳定。灯和催化剂。光化学获得的Z异构体显示出随着脂肪族环的尺寸增加而形成三环内酯的趋势增加。E和E的理论结构分析Z异构体,三环内酯和与肼反应的一些假设中间体表明,脂族环的大小和相关的柔韧性对于调节这些化合物形成三环产物的能力至关重要。

The invention relates to novel tricyclic 1,2,4-triazine-1-oxides and novel tricyclic 1,2,4-triazine-1,4-dioxides of formula I
and to related analogues, to their preparation, and to their use as hypoxia-selective drugs and radiosensitizers for cancer therapy, both alone or in combination with radiation and/or other anticancer drugs.
switch in the configuration of aza-Michaelreaction products is described. Depending on both the stereochemical purity and stoichiometric ratio of the chiral amine used, the reaction delivers crystalline diastereomers of a different stereochemistry. The optically pure diastereomer smoothly converts to its racemic epimer salt upon the addition of a complementary chiral amine.
