  使用原位生成的甲基（三氟甲基）二环氧乙烷对芳基恶唑啉进行氧化裂解

  摘要：

  使用原位生成的甲基（三氟甲基）二环氧乙烷1a对芳基恶唑啉2进行氧化裂解，可得到中间体硝基酯8，该中间体经过碱性水解以提供苯甲酸11。甚至受阻的恶唑啉7也可以平滑地裂解，得到3,3'-二甲基-2,2'-二苯甲酸16。所有取代的苯甲酸11-16都可以优良的产率（80-95％）分离出来。

  Mazindol Analogues as Potential Inhibitors of the Cocaine Binding Site at the Dopamine Transporter

  摘要：

  A series of mazindol. (2) and homomazindol (3) analogues with a variety of electron-donating and electron-withdrawing groups in the pendant aryl group and the benzo ring C, as well as H, methoxy, and alkyl groups replacing the hydroxyl group were synthesized, and their binding affinities at the dopamine transporter (DAT) on rat or guinea pig striatal. membranes were determined. Several active analogues were also evaluated for their ability to block uptake of DA, 5-HT, and NE and inhibit binding of [I-125] RTI-55 at HEK-hDAT, HEK-hSERT, and HEK-hNET cells. Mazindane (26) was found to be a pro-drug, oxidizing (5-H --> 5-OH) to mazindol on rat striatal membranes and HEk-hDAT cells. The 4',7,8-trichloro analogue (38) of mazindol was the I most potent and selective ligand. for HEK-hDAT cells (DAT K-i = 1.1 nM; SERT/DAT 1283 and NET/DAT = 38). Experimental results strongly favor the cyclic or ol tautomers of 2 and 3 to bind more, tightly at the DAT than the corresponding keto tautomers.

  bond was developed using aryl acylperoxides as inexpensive aryl sources. Substrates containing pyridyl, oxime, and oxazoline groups undergo effectively ortho-selective C−H arylation with excellent functional group tolerance. This arylation should begin by directing-group-assisted cyclopalladation, followed by the reaction of the palladacycle with aryl radicals generated in situ by thermal decomposition

  The rhodium(I)‐catalyzed extrusion of carbon monoxide from biaryl ketones and alkyl/alkenyl aryl ketones was developed to produce biaryls and alkyl/alkenyl arenes, respectively, in high yields (see scheme). A wide range of functionalities are tolerated. Not only does this method provide an alternative pathway to construct useful scaffolds, but also offers a new strategy for CC bond activation.
