Stereoselective synthesis of hydroxyindolizidines via sparteine-assisted deprotonation of N-Boc-pyrrolidine
摘要:
Three diastereoisomers of 1-deoxycastanospermine were synthesized in enantiomerically pure form. The key step in the synthesis involved reaction of lithiated N-Boc-pyrrolidine in the presence of sparteine with a chiral building block derived from tartaric acid. (C) 1998 Elsevier Science Ltd.
