SYNTHESIS OF SECOISOQUINOLINE ALKALOIDS. TOTAL SYNTHESIS OF SAXOGUATTINE

A total synthesis of saxoguattine (1) was performed by using aldehyde 4 and isovanillin 1,3-propylene dithioacetal (5) as building blocks.The formation of C-C bond between them was the key step in the synthesis and involved addition of dilithio salt of di
