An enantioselective synthesis of carbafuranose sugars based on a linchpin carbacyclisation approach
摘要:
Enantiopure carbafuranose derivatives were synthesised via a linchpin carbacyclisation process starting from 1,4-bisepoxides. Both 2-deoxy and 2-deoxy-6-hydroxycarbafuranose derivatives were obtained, which were converted to suitably protected precursors for carbanucleoside synthesis. (C) 2009 Elsevier Ltd.
