英文摘要 | Bis(4-methoxyphenyl)methanol (2a) can be transformed by BF3 center dot OEt2-catalyzed reactions of (arylmethylene)cyclopropanes 1 to the corresponding polysubstituted cyclopentenes 3 as the major products along with methylenecyclobutanes and dienes as minor products. The reaction conditions are mild, yields are moderate to good. In the reactions of aliphatic methylenecyclopropanes with bis(4-methoxyphenyl)methanol (2a), cyclopentenes 3o-q were produced in good yields under the standard conditions. Interesting results were obtained from the reactions of 1-[cyclopropylidene(4-methoxyphenyl)methyl]-4-methoxybenzene (1e) with bis(4-alkoxyphenyl)methanols 2: polysubstituted cyclopentene derivatives 5 were obtained in good yields under mild reaction conditions. Plausible reaction mechanisms based on the deuterium-labeling and control experiments are proposed. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009) |
