Effect of remote heteroatom substituents on stereochemistry in 1,2 h migration to divalent carbon. Evidence for “negative” hyperconjugation of carbene lone pair
Aryloxymethylchlorocarbene generated by photolysis of the corresponding diazirine afforded α-aryloxy-β-chloroalkene. The thermodynamically less stable Z-products are the major isomers and its content becomes dominant as more electron-withdrawing groups are introduced on phenyl ring.

The present invention relates to inhibitors of 11-β-hydroxysteroid dehydrogenase type 1 enzyme and their use in treatment of non-insulin dependent type 2 diabetes, insulin resistance, obesity, lipid disorders, metabolic syndrome, central nervous system disorders, and diseases and conditions that are related to excessive glucocorticoids.
procedure is described for the synthesis of 2-substituted perimidines involving the reaction of 1,8-diaminonapthalene with iminoester hydrochlorides of substituted phenylacetic acids under microwave irradiation. This leads to good yields in short reaction times. The results were compared with those that used conventional heating. This new method may be preferable for the synthesis of perimidines.

Derivatives of imidazo[4,5-c]pyridlne (IP) show a variety of pharmacological activities [3, 9]. In particular, there are IP derivatives active as GABAergir agonists and selective anxiolytic antagonists [2, 8]. To investigate the neurotropic activity of IP derivatives, four compounds (la-d) were prepared with adamantyl, dipropylmethyl, 4-chlorophenoxymethyl, and pyridyl-3-oxymethyl moieties as the pharmacophore
咪唑并 [4,5-c] 吡啶 (IP) 的衍生物显示出多种药理活性 [3, 9]。特别是,有作为 GABAergir 激动剂和选择性抗焦虑拮抗剂的 IP 衍生物 [2, 8]。为了研究 IP 衍生物的神经活性,制备了四种化合物 (la-d),其中金刚烷基、二丙基甲基、4-氯苯氧基甲基和吡啶基-3-氧基甲基部分作为 IP 位置 2 的药效基团。
