Treatment of allylic chloride 18E, derived from D-glucose, with NaH in the presence of a catalytic amount of Pd(Ph 3 P) 4 provided a piperidine derivative 19 with high diastereoselectivity. Further functional group transformation from 19 completed enantiospecific total syntheses of (-)-desoxoprosopinine 3 and (-)-desoxoprosophylline 4.
