• overall yield of 2%. Mander’s synthesis of sordaricin As early as 1991, Mander reported model studies [24][25] for sordaricin synthesis using intramolecular [4+2] cycloaddition, and this work culminated in a total synthesis of Sordaricin in 2003 [14][15].

• unsubstituted and α- or β-methyl substituted 2-cycloenones was also observed. Introduction For more than 70 years, the Diels-Alder reaction, or [4+2] cycloaddition reaction, has remained as one of the best powerful organic transformations in chemical synthesis, particularly in obtaining polycyclic rings.
