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 rearrangement of the precursor bearing hydroxy group of C-8 was also described.
河豚毒素及其类似物的关键中间体,如(-)-5,11-二脱氧河豚毒素,是通过手性原料左旋葡糖醛酮通过Diels-Alder反应和超人重排立体合成的。还描述了带有C-8羟基的前体的超载重排。
