Abstract
A new class of di(α-aminophosphonate) pesticides were prepared by the Kabachnik-Fields reaction under solvent- and catalyst-free conditions with microwave irradiation, and the products were obtained in good-to-excellent yields at shorter reaction time. These compounds were characterized by IR, (1)H, (13)C, (31)P NMR, and mass spectral data. Among them, compounds 4f, 4c, and 4h showed good pesticidal activity against Spodoptera litura, with 92.6, 91.3, and 89.3% mortality.
