Synthesis of (−)-dihydropinidine, (2S,6R)-isosolenopsin and (+)-monomorine via a chiral synthon from l-aspartic acid
摘要:
The use of beta-amino aldehyde derived from L-aspartic acid as a chiral synthon to construct 2,6-disubstituted piperidines is described. The synthesis of (-)-dihydropinidine center dot HCl, (2S,6R)-isosolenopsin center dot HCl and (+)-monomorine has been achieved from this chiral synthon using a Wittig reaction followed by hydrogenation (reductive cyclization) as the key steps.
