A generic small-molecule microarray immobilization strategy
摘要:
Small-molecule microarrays are often limited by the requirement for each compound undergoing immobilization to contain a common functional group or by the need to prepare glass slides containing photo-reactive groups. Herein, we present a generic strategy that allows any compound library to be immobilized. This was achieved by printing a fluorous-tagged photo-reactive 3-aryl-3-trifluoromethyldiazirine, which undergoes non-selective insertion into compounds following UV-activation, onto fluorous-functionalized glass slides. The arrays could be reused following aqueous stripping and re-assessment of the compounds with the same protein or another target of interest. Crown Copyright (C) 2011 Published by Elsevier Ltd.

An efficient and metal-free method was developed to synthesize 3-chalcogen benzo[b]furans via the iodine-mediatedelectrophilic cyclisation of 2-alkynylanisoles with disulfides or diselenides. In the presence of I2, various 3-sulfenylbenzofurans or 3-selenenylbenzofurans were obtained in moderate to high yields.
通过用二硫化物或二硒化物通过碘介导的2-炔基茴香醚的亲电亲电环化反应,开发了一种高效且无金属的方法来合成3-硫属元素苯并[ b ]呋喃。在I 2的存在下,以中等至高产率获得了各种3-亚磺酰基苯并呋喃或3-硒代苯并呋喃。
