A general approach for the synthesis of novel 2-fluoro-3-phenylthio-1,3-butadiene (8) and 2-trifluoromethyl-3-phenylthio-1,3-butadiene (9) from monobromoalkene and dibromoalkenes has been developed. Subsequent Diels−Alder reactions of these dienes with symmetrical and unsymmetrical dienophiles in the presence of Lewis acids gave a variety of fluorinated six-membered carbocycles in moderate to high
已经开发了从单溴代烯烃和二溴代烯烃合成新型2-氟-3-苯基硫代-1,3-丁二烯(8)和2-三氟甲基-3-苯基硫代-1,3-丁二烯(9)的通用方法。随后这些二烯在路易斯酸存在下与对称和不对称亲二烯体的Diels-Alder反应以中等至高收率得到了多种氟化的六元碳环。
