Studies on the Syntheses of Heterocyclic Compounds. CDLXXXVII. Photolytic Synthesis and Rearrangement of Proerythrinadienones

Photolysis of the 1-(2-bromobenzyl)-1, 2, 3, 4-tetrahydro-7-hydroxyisoquinolines (VII, VIII, and X) gave the proerythrinadienones (XIII, XIV, and XV), which would be key precursors for several isoquinoline alkaloids. The acidic treatment of these dienones and the corresponding dienols (XXXII) was in...

Summary:Photolysis of the 1-(2-bromobenzyl)-1, 2, 3, 4-tetrahydro-7-hydroxyisoquinolines (VII, VIII, and X) gave the proerythrinadienones (XIII, XIV, and XV), which would be key precursors for several isoquinoline alkaloids. The acidic treatment of these dienones and the corresponding dienols (XXXII) was investigated under several conditions.
