Stereoselective synthesis of swainsonines from pyridines
Heimg?rtner, Gerres,Raatz, Dirk,Reiser, Oliver
, p. 643 - 655 (2007/10/03)
An efficient synthesis of (-)-swainsonine and (-)-2,8a-di-epi-swainsonine was developed starting from readily available 2-pyridinecarbaldehyde and 3-hydroxypyridine. In particular, it was demonstrated that the mixture of simple indolizidines, i.e. lentigi
