描述了通过用多甲基三甲基甲硅烷基环化N-酰基-N'-芳基三亚甲基二胺2来合成1-芳基-2-烷基-1,4,5,6-四氢嘧啶1的通用方法。前体2通过相应的N-(3-溴丙基)酰胺3的氨解获得。分析了四氢嘧啶1的1 H nmr光谱,讨论了杂环1和2位上取代基的影响。化合物1的碱性水解,仅源于N-酰基-N'-芳基三亚甲基二胺2还通过中间体甲醇胺进行了研究。根据立体电子控制理论讨论了这种中间体的裂解。用硼烷还原化合物1会导致区域特异性地导致N-烷基-N'-芳基三亚甲基二胺6。

This invention provides rhenium tricarbonyl complexes and their use in the treatment of cancer and inhibition of Aurora kinase. The rhenium tricarbonyl complexes comprise a C-donor N-heterocyclic carbene (NHC) ligand. Also provided are processes for the preparation of the rhenium complexes.
We here report the affinity purification of N-acylhomoserine lactone synthases using beads conjugated with an enzyme inhibitor, which was designed based on the catalytic intermediate acyl-SAM.
0.5 nM and excellent selectivity (>4000-fold) over the CB1 receptor. The size of the substituent on the 2-position determined the level of agonism, ranging from inverseagonism to partial agonism to full agonism, which was more pronounced for the rat CB2 receptor. A wide variation of sulfonyl substituents at the benzimidazole 5-position was tolerated, which was used to optimize the drug-like properties
Phenoxypropylamine derivatives of the general formula ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl or ethyl group, R.sub.2 and R.sub.3, independently from each other, represent a lower alkyl group, or together form a linear alkylene group having 4 to 7 carbon atoms which may be optionally substituted by a hydroxyl or hydroxymethyl group, and R.sub.4 represents a hydrogen atom or a group of the formula --R.sub.5 --Z in which R.sub.5 represents a lower alkylene group, and Z represents a hydrogen atom or an amino, mono- or di-(lower alkyl)-amino, hydrdoxy lower alkylamino, lower alkanoylamino, hydroxyl, lower alkoxy, lower alkanoyloxy, phenoxy, halophenoxy, benzoyloxy or halobenzoyloxy group, and the salts thereof; to a process for production thereof; and to their medicinal use, particularly to antiulcer agents comprising these phenoxypropylamine derivatives or their salts.
