Synthesis of 1-deoxy-D-galactohomonojirimycin via enantiomerically pure allenylstannanes. | LitMetric

Synthesis of 1-deoxy-D-galactohomonojirimycin via enantiomerically pure allenylstannanes.

J Org Chem

Department of Chemistry, Colorado State University, Fort Collins, Colorado 80523, USA.

Published: April 2004

1-Deoxy-D-galactohomonojirimycin was synthesized in seven steps from optically pure allenylstannane 4 and L-lactate-derived aldehyde 5 in 48% overall yield. The key step was the Lewis acid catalyzed reaction of 4 and 5 to give the syn-amino alcohol in excellent yield and very high diastereoselectivity.
