Title: | Synthetic protocols towards homodithiacalix[n]arenes | Authors: | Thomas, Joice Dobrzanska, Liliana Sonawane, Mahendra Punjaji Smet, Mario MAES, Wouter Dehaen, Wim |
Issue Date: | 2014 | Publisher: | TAYLOR & FRANCIS LTD | Source: | SUPRAMOLECULAR CHEMISTRY, 26 (7-8), p. 591-596 | Abstract: | Synthetic procedures towards homodithiacalix[n]arenes are developed, starting from simple and readily available bifunctional aryl building blocks, by a dynamic covalent chemistry approach. Reaction of 1,3-bis(mercaptomethyl)-5-tert-butyl-2-methoxybenzene under basic conditions leads to a mixture of trimeric, tetrameric and pentameric dimethylenedithia-bridged cyclooligomers, whereas reaction of 5-tert-butyl-2-methoxy-1,3-bis(thiocyanatomethyl) benzene under reducing conditions (and subsequent oxidation) affords the homodithiacalix[4]arene macrocycle in a very selective fashion through efficient disulphide exchange chemistry. | Notes: | [Thomas, Joice; Dobrzanska, Liliana; Sonawane, Mahendra Punjaji; Smet, Mario; Dehaen, Wim] Katholieke Univ Leuven, Dept Chem, B-3001 Leuven, Belgium.
