摘要
A facile and efficient synthesis of dihydrooxepins is described. Treatment of readily available 2-amino-4,5-dihydro-3-furancarbonitriles with dimethyl acetylenedicarboxylate at room temperature caused smoothly a cycloaddition reaction, followed by a ring expansion, giving the corresponding dihydrooxepin derivatives.
