E. Martinez et al., Total syntheses of 1-methyl-1,2,3,4-tetrahydronaphtho[2,1-f]- isoquinolines involving free radical cyclizations induced by tributyltin(IV) hydride, TETRAHEDRON, 57(10), 2001, pp. 1973-1979
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}acetamide
s and subsequent transformation of the resulting N-[2-(10-methoxy-9, 10-dih
ydro-1-phenanthryl)ethyl]acetamides. The second is based on the known cycli
zation of 1-(2-bromobenzyl)isochroman-3-ones to 4,5, 6a,7-tetrahydrodibenzo
[de,g]chroman-3-ones followed by transformation of the resulting 2-(1-phen
anthryl)acetamides. (C) 2001 Elsevier Science Ltd. All rights reserved.
