- 中文摘要: Three-component condensation of ninhydrin, malononitrile, and some nucleophilic reagents in the presence of piperidine under microwave irradiation without solvent afforded the corresponding spiro-fused pyran derivatives. The structures of the products were proved by elemental analyses, IR, 1H NMR and MS spectroscopy.
