1,4-Dehydrochlorination of 1-(1-haloalkyl)-3,4-dihydroisoquinolines as a convenient route to functionalized isoquinolines
摘要:
1-Chloroalkyl-, 1-(2,2-dichloroalkyl)-, and 1-(trichloromethyl)-3,4-dihydroisoquinolines are synthesized by chlorination of 1-alkyl-3,4-dihydroisoquinolines with N-chlorosuccinimide. These novel chlorinated 3,4-dihydroisoquinolines are suitable precursors for functionalized isoquinolines by aromatization involving sequential 1,4-dehydrochlorination, tautomerization, and nucleophilic substitution.
