THE CHEMISTRY OF VICINAL TRICARBONYL COMPOUNDS. APPLICATIONS IN THE SYNTHESIS OF ISOQUINOLINE ALKALOIDS

The central carbonyl of a vicinal tricarbonyl system is used as a dielectrophile with substituted phenethylamines in short, efficient syntheses of the isoquinoline alkaloids, papaveraldine, hydrastine and cordrastine.

Synthesis of isoindolobenzazepines via photocyclization of N-(2-formyl phenethyl)phthalimide derivatives

Reaction of imine 2 with ester acid chloride 3 gives aldehydic phthalimide 4 which on treatment with dithiols (n = 2, 3) yields the thioacetal 5.Photolysis of 5 furnish cyclic product 6(a-c).Desulphurisation of 6a affords lennoxamine model 7.Deketalisatio
