1-4-Alkynediols serve as readily available starting materials for isomerisation to 1,4-diketones, which can be converted in situ into the corresponding furans by acid-catalysed dehydration. A range of 2,5-disubstituted furans was prepared using the ruthenium-based catalyst Ru(PPh3)(3)(CO)H-2 with Xantphos at 1 mol % loading. (C) 2007 Published by Elsevier Ltd.

A heart of gold: Phenols can be obtained by the intermolecular reaction of furans with alkynes by using [AuIPr]+A− catalysts (see scheme). 1,3‐Diphenylisobenzofuran also reacts via a cyclopropyl gold carbene to selectively form 2,3‐disubstituted indenes. (IPr=1,3‐bis(2,6‐diisopropylphenyl)imidazol‐2‐ylidene; A=anion.)
金的心脏:酚类可以通过与炔呋喃的分子间反应,通过使用[AuIPr]可以获得+甲-催化剂(参见方案)。1,3-二苯基异苯并呋喃也通过环丙基金卡宾反应,选择性地形成2,3-二取代的茚。(IPr = 1,3-二(2,6-二异丙基苯基)咪唑-2-亚基; A =阴离子。)
