Starting from (+)-17,18-dehydroapovincamine, a new δ-lactone bridged apovincamine derivative (6) was synthesized in two steps involving oxidative hydroboration followed by catalytic hydrogenation. The structure elucidation of this compund, the intermediate and the by-products was performed by IR, 1H- and 13C-NMR methods including DNOE measurements.
