Stereoselective total synthesis of (2S,3R)-3-hydroxypipecolic acid
摘要:
A concise, stereocontrolled synthesis of (2S,3R)-3-hydroxypipecolic acid 1 is described. Key features involve diastereoselective oxazoline formation catalyzed by palladium(0) and intramolecular cyclization by catalytic hydrogenation of an oxazoline. (C) 2008 Elsevier Ltd. All rights reserved.

We report a new asymmetric synthetic method for (−)-swainsonine utilizing a chiral oxazoline precursor. The key features in this strategy are the diastereoselective oxazoline formation reaction catalyzed by palladium(0), diasteroselective dihydroxylation, and the stereocontrolled allylation reaction with TiCl4.
