TOTAL SYNTHESIS OF PSEUDO TYPE OF PROTOPINE ALKALOIDS

Photolysis of the chloroacetamides (1) gave the benzazepinones (2), whose benzyl derivatives (3) were cyclized to the benz-indenoazepines (4) by treatment with phosphoryl chloride.DYe-sensitized photo-oxygenation of 4, followed by lithium aluminum hydride reduction and manganese dioxide oxidation of the products 5, led to a total synthesis of pseudoprotopine (7a) and fagarine II (7b) as well as their analogs 7c and 7d.
