  Cyclohydrocarbonylation-Based Strategy toward Poly- Substituted Piperidines

  摘要：

  Convenient accesses to enantiomerically pure 2-, 2,3-, 2,6-, 2,3,6-substituted piperidines and 1,4-substituted indolizine are described. At first, indium-mediated aminoallylation and -crotylation of aldehydes with (R)-phenylglycinol or (1R,2S)-1-amino-2-indanol gave homoallylamines with high stereocontrol. Then, these products, submitted to a Rh(I)-catalyzed hydroformylative cyclohydrocarbonylation, afforded perhydrooxazolo [3,2-a]piridines whose oxazolidines are opened with nucleophiles. Finally, the removal of the chiral auxiliaries delivered the enantiomerically pure piperidines.
