An Efficient Synthesis of Heterocyclic Analogs of 1-Arylnaphthalene Lignans

The heterocyclic analogs 5a-f, 16, and 20 of 1-arylnaphthalene lignans were synthesized by Diels-Alder reactions of acetoxy aldehydes 11a-f, 14, and 18 with dimethyl acetylenedicarboxylate.A pathway for formation of 5a-f, 16, and 20 through the intermediacy of heteroaromatic isobenzofurans derived from acetoxy aldehydes is discussed.
