N-ethoxycarbonyl-1-amino-1-(2-vinylphenyl)-2-phenylethylenes, which can be transformed into 3-(2-vinylphenyl)-2-methyl-2H-isoquinolin-1-ones by Bischler–Napieralski reactions, and thence into benzo[c]phenanthridin-6-ones. The use of this route for a new total synthesis of fagaronine is described.
用LDA处理N-碳乙氧基-1-亚苄基异喹啉可得到N-乙氧基羰基-1-氨基-1-(2-乙烯基苯基)-2-苯基乙烯,可以将其转化为3-(2-乙烯基苯基)-2-甲基-2。H-异喹啉-1-酮通过Bischler-Napieralski反应,并由此生成苯并[ c ]菲啶-6-酮。描述了将该途径用于新的全合成法格罗宁的用途。
