  摘要：

  A novel intramolecular Prins cyclization of (E)-5-(2-(hydroxymethyl)phenyl)pent-4-en-1-ol with aldehydes has been achieved using 10 mol % BF3 center dot Et2O to produce 1-(tetrahydropyran-3-yl)-1,3-dihydroisobenzofuran derivatives in good to excellent yields with high selectivity. Similar type of coupling with salicylaldehydes provides the trans-fused hexahydropyrano[3,2-c]chromene derivatives in excellent yields. (C) 2014 Published by Elsevier Ltd.

  We synthesized [6,6,6]- and [6,6,7]-tricyclic compounds via intramolecular [4+2] cycloaddition by gold or copper catalysts. Substrates for cyclization were prepared by coupling reactions between eight types of diyne and four types of aromatic moieties. We have successfully synthesized eleven tricyclic compounds.

  We report the discovery of an anomalous reaction of 2-(alkynonyl)alkynylbenzenes under AgI catalysis for the selective formation of isocoumarins. This reaction is previously undocumented for 2-(alkynonyl)alkynylbenzenes in terms of the reaction mechanism and the product formed. Water (H2 O18 ) labeling studies suggested a possible mechanistic pathway in which the initial formation of a pyrylium ion

  我们报告了2-（炔基）炔基苯在AgI催化下选择性形成异香豆素的反常反应的发现。就反应机理和形成的产物而言，对于2-（炔基）炔基苯，该反应以前没有记载。水（H2 O18）标记研究表明，可能的机理途径是，首先形成吡咯鎓离子，然后进行水合脱羰基化反应，即水掺入和炔烃排出，这与法维斯基逆反应相似。

  ortho-Carbonylarylacetylenols have been employed for the synthesis of dihydronaphthofurans via AgTFA-catalyzed annulation reaction. A broad range of substrates both ortho-keto- and ortho-formylarylacetylenols could be employed in this transformation providing the desired products in good yields. However, the reaction pathways of these two substrates are different. The reaction of the ketone precursors could directly

  邻-羰基芳基乙酰基烯醇已被用于通过AgTFA催化的环化反应合成二氢萘呋喃。在该转化中可以使用邻-酮-和邻-甲酰基芳基乙酰基烯醇的各种各样的底物，以高收率提供所需的产物。但是，这两种底物的反应途径是不同的。酮前体的反应可在一次操作中直接产生所需的产物，而醛前体的反应则需要一锅两步的方法，而无需分离双环缩醛中间体。此外，该方法还以很高的产率成功地用于合成二氢萘并吡喃。
