A SYNTHETHIC ROAD TO THE FOREST OF STRYCHNOS, ASPIDOSPERMA, SCHIZOZYGANE AND EBURNAMINE ALKALOIDS BY WAY OF THE NOVEL PHOTOISOMERIZATION

The novel photoisomerization of 1-acylindoles accompanied by a conversion of indole to indolenine afforded 3-acylindolenines, a so far unknown reactive species, as a major product.This reaction was thorougly investigated and applied with success to the total synthesis of Strychnos, Aspidosperma, Schizozygane and Eburnamine alkaloids through a versatile intermediate 9-membered ring system,synthesized in a one pot reaction by photolysis and the simultaneous ring enlargement.
