The highly functionalized piperidine 5a was synthesized in only 4 steps starting from ribose using a tandem retro-Michael-[2+3]-cycloaddition process as the key transformation. The versatility of the tandem retro-Michael-[2+3]-cycloaddition was demonstrated by the synthesis of novel piperidines 5b, 5c, 11 and 16.
