Two new total syntheses of 1-methyl-1,2,3,4-dihydronaphtho[1,2-f]isoquinolines are based on the construction of their phenanthrene ring system by photochemically induced cyclization of N-2-[(E)-2-phenyl-1-ethenyl]phenylethyl}acetamides or 1-methyl-5-[(E)-2-phenyl-1-ethenyl]-1,2,3,4-tetrahydroisoquinolines.
1-甲基-1,2,3,4-二氢萘并[1,2- f ]异喹啉的两个新的总合成是基于通过光化学诱导的N- 2-[(E) -2-苯基-1-乙烯基]苯基乙基}乙酰胺或1-甲基-5-[(E)-2-苯基-1-乙烯基] -1,2,3,4-四氢异喹啉。
