A new approach to 2,6-disubstituted tetrahydropyrans by a tandem cross-metathesis/iodocyclisation reaction has been developed. The stereochemical outcome of the cyclisation reactions has been studied for different substrates. This sequence has allowed the preparation of a series of cis- and trans-2,6-disubstituted analogues of the tetrahydropyran subunit of bistramide A.(© Wiley-VCH Verlag GmbH & Co
已经开发出一种通过串联交叉复分解/碘环化反应制备 2,6-二取代四氢吡喃的新方法。已针对不同底物研究了环化反应的立体化学结果。该序列允许制备双酰胺 A 的四氢吡喃亚基的一系列顺式和反式 2,6-二取代类似物。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
