Synthesis of a common key intermediate for (-)-tetrodotoxin and its analogs

A key intermediate for tetrodotoxin and its analogs such as (-)-5,11-dideoxytetrodotoxin was stereoselectively synthesized from a chiral starting material, levoglucosenone, via Diels-Alder reaction and the Overman rearrangement as key steps. The Overman r
