Levoglucosenone-derived precursors for the stereoselective synthesis of methylene-expanded analogues of C-nucleosides
摘要:
Simple chiral precursors for the preparation of methylene-expanded C-nucleosides were developed, using as key steps pyrolysis of cellulose to levoglucosenone followed by hydrogenation and introduction of vinyl and ethynyl fragments to the 2-position.
