The pyran-opyran amide (2<i>S</i>,4a<i>R</i>,8a<i>R</i>)-6-oxo-2,4a,6,8a-tetra-hydro-pyrano[3,2-<i>b</i>]pyran-2-carboxamide, C<sub>9</sub>H<sub>9</sub>NO<sub>4</sub>, <b>3</b>, was prepared by a chemoselective hydration of the corresponding nitrile, <b>2</b>, using a heterogeneous catalytic method based on copper(II) supported on mol-ecular sieves, in the presence of acetaldoxime. Compound <b>3</b> belongs to a new class of pyran-opyrans that possess anti-bacterial and phytotoxic activity. Crys ...[more]
