Pentacyclic analogues of the potent voltage-gated sodium ion channel agonist batrachotoxin can be accessed through an intermediate furan by exploiting Diels-Alder cycloaddition reactions with ring-strained dienophiles. The use of 3-bromofuran as a 1,2-dianion equivalent, the application of carbamate reductive N-alkylation for homomorpholine ring assembly, and the demonstration of CsF as an effective
强大的电压门控钠离子通道激动剂巴曲毒素的五环类似物可通过利用呋喃环与Diels-Alder环加成反应与环应变的亲二烯体接触而通过中间呋喃获得。使用3-溴呋喃作为1,2-阴离子等效物,应用氨基甲酸酯还原性N-烷基化作用制备同型吗啉环,以及证明CsF作为产生苯并,环己和相关亲二烯体的有效试剂的研究强调了这项工作。
