Efficient asymmetric syntheses of alkaloids and medicinally relevant molecules based on heterocyclic chiral building blocks

Abstract

AbstractIn this report, we present recent progress in synthetic methodologies based on three heterocyclic chiral building blocks developed from our laboratories. The potential of these chiral building block-based methods in the concise asymmetric synthesis of alkaloids and medicinally interesting molecules has been demonstrated by the total syntheses of 8-aza-prostaglandin E1, 11-hydroxylated analogues of the lead compounds CP-734432 and PF-04475270, (+)-castanospermine, (+)-1-epi-castanospermine, 7-deoxy-6-epi-castanospermine as well as 9-epi-sessilifoliamide J.
