Significance
The synthesis of nicolaioidesin C exemplifies a general procedure for effecting electron transfer initiated Diels-Alder reactions of 2-hydroxychalcones with 1,3-dienes. The procedure uses either Co(I) or BH4 - as the electron transfer agent in the presence of ZnI2 as a bidentate Lewis acid. The mechanism proposed accounts for the formation of a single trans diastereoisomer.
