We describe two total syntheses of 1-methyl-1,2,3,4-tetrahydronaphtho[1,2-f]isoquinolines based on free radical cyclization. One of them includes the cyclization of N-2-[2-(2-bromophenyl)-1-methoxyethyl]phenylethyl}acetamides and subsequent transformation of the resulting N-[2-(10-methoxy-9,10-dihydro-1-phenanthryl)ethyl]acetamides. The second is based on the known cyclization of 1-(2-bromobenzyl)isochroman-3-ones
我们描述了基于自由基环化的1-甲基-1,2,3,4-四氢萘并[1,2- f ]异喹啉的两个总合成。其中之一包括将N- 2- [2-(2-溴苯基)-1-甲氧基乙基]苯基乙基}乙酰胺环化,然后转化所得的N- [2-(10-甲氧基-9,10-二氢- 1-菲基)乙基]乙酰胺。第二种方法是基于已知的将1-(2-溴苄基)异色满-3-酮环化为4,5,6a,7-四氢二苯并[ de,g ]色满-3-酮,然后转化所得的2-( 1-菲基)乙酰胺。
