chromatography after transformation of the nitrogen protective benzyl group into the corresponding carbamates 14 and 15. Both compounds, after elaboration of the chain geminal to the nitro group into a vinyl appendage. underwent regio- and stereo-selective removal of the nitro group by palladium-catalyzed displacement with hydride generated by formate to give the precursor 19, easily converted by treatment
