Deskripsi

As part of our ongoing scaffold hopping work on antimalarial 2-aminothieno[3,2-<i>d</i>]pyrimidin-4-one scaffold, we explored the dihydrothieno[3,2-<i>d</i>][1,3,2]diazaborinin-4(1<i>H</i>)-one as a potential new antimalarial series. Using conditions found in the literature, we obtained 2-cyclopropyl-6-phenyl-2,3-dihydrothieno[3,2-<i>d</i>][1,3,2]diazaborinin-4(1<i>H</i>)-one with 93% yield through a simple treatment. It was then characterized by NMR (<sup>1</sup>H and <sup>13</sup>C) and HRMS. Given the structure of this molecule, its aqueous stability was assessed to determine its suitability for biological tests. To our knowledge, this is the first dihydrothieno[3,2-<i>d</i>][1,3,2]diazaborinin-4(1<i>H</i>)-one described.
