A novel cyclization process of 2,3-bis(trimethylsilyl)buta-1,3-diene with various acyl chlorides in the presence of aluminium trichloride affords 2,5-disubstituted or 2,3,5-trisubstituted furans in short reaction time; a subsequent acylation process of the furan ring occurs if the reaction time is prolonged.
在三氯化铝存在下,用各种酰氯对2,3-双(三甲基甲硅烷基)丁1,3-二烯进行新颖的环化反应,可在较短的反应时间内得到2,5-二取代或2,3,5-三取代的呋喃。如果反应时间延长,则呋喃环随后发生酰化过程。
