  Tosylhydrazine mediated conjugate reduction and sequential reductive coupling cyclization: synthesis of 2-arylchromans

  摘要：

  Tosylhydrazine mediated conjugate reduction of 2-hydroxyl chalcones and sequential reductive coupling cyclization is described. This is an unprecedented protocol and an extremely efficient method for a one-pot domino synthesis of 2-arylchromans in good to excellent yields from commercially available, cheap starting materials. More importantly, the two-step reactions can be easily controlled to afford dihydrochalcones or 2-arylchromans by the mole amounts of tosylhydrazine. Furthermore, the operational simplicity of the process and the high functional group tolerance are remarkable. (C) 2015 Elsevier Ltd. All rights reserved.

  Novel compounds of formula (IID) ##STR1## wherein either both X and Y represent groups independently selected from amino and lower alkylamino, or one of X and Y represents a group selected from amino and lower alkylamino and the other of X and Y represents a hydrogen atom have been found to be active against rhinoviruses and other viruses. Processes for producing these compounds include reduction of flavanone derivatives or of flavenes. Alternatively, reductive cyclization of chalcones affords the compounds. These may also be prepared by condensation of o-(substituted methyl)phenols with styrene derivatives. Pharmaceutical formulations and methods for the administration of the compounds are described.

  已经发现了具有公式(IID)的新化合物##STR1##，其中X和Y中的一个或两个分别选自氨基和较低的烷基氨基，或者X和Y中的一个代表氨基或较低的烷基氨基，另一个代表氢原子，这些化合物已被发现对鼻病毒和其他病毒具有活性。制备这些化合物的方法包括还原黄酮酮衍生物或黄酮类化合物。另外，还可以通过还原环化的方式合成这些化合物。这些化合物也可以通过对邻位取代的甲基苯酚与苯乙烯衍生物的缩合来制备。还描述了这些化合物的制药配方和给药方法。

  An efficient one-pot synthesis of O-heterocycles or aryl ketones has been achieved using Et3SiH in the presence of InCl3 via a sequential ionic hydrogenation reaction by switching the solvent. This methodology can be used to construct C–O bonds and to prepare conjugate reduction products, including chromans, tetrahydrofurans, tetrahydropyrans, dihydroisobenzofurans, dihydrochalcones, and 1,4-diones

  使用Int 3 SiH的Et 3 SiH通过转换溶剂进行顺序离子氢化反应，可以在InCl 3存在下实现O-杂环或芳基酮的有效一锅合成。该方法可用于轻松构建C–O键并制备共轭物还原产物，包括苯并二氢吡喃，四氢呋喃，四氢吡喃，二氢异苯并呋喃，二氢查耳酮和1,4-二酮。另外，通过实验研究证实了涉及共轭物还原和串联还原性环化的新型合理机制。
