Synthesis of Tri-O-acetyl-d-allal from Levoglucosenone
摘要:
Tri-O-acetyl-o-allal has been enantiospecifically synthesized in six steps from levoglucosenone in 55% overall yield. A key step in the synthesis is the anhydro bridge ring-opening with concomitant formation of a 1,3-oxathiolane-2-thione ring.
