A variety of polysubstituted 3-iodopyrans were readily prepared in good to excellent yield under mild reaction conditions by the reaction of alkynyl carboxamides with ICl, I(2), and NIS. The products obtained from this process are versatile materials that can be used to construct other complex functionalized pyran structures of importance. The occurrence of the pyranyl group in both natural products
在温和的反应条件下,通过炔基羧酰胺与 ICl、I(2) 和 NIS 的反应,可以很容易地制备出多种多取代的 3-碘吡喃,并以良好的产率获得优异的产量。从该过程中获得的产品是多功能材料,可用于构建其他重要的复杂功能化吡喃结构。天然产物和药物中吡喃基的出现为本研究带来了重要价值。((c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
