SYNTHESIS OF THE MONOTERPENE ALKALOID BAKANKOSIN FROM SECOLOGANIN
Reduction of secologanin 1a with sodium borohydride followed by acylation afforded 86percent of sweroside tetraacetate 4 which was transformed to the 8-iodomethylester 5c by treatment with trimethylsilyliodide, hydrolysis and addition of diazomethane in 9
