In natural product synthesis, the procurement of easily accessible starting materials is crucial. Chromenones and their subclass, coumarins, are a wide family small, oxygen-containing aromatic heterocycles. Phenylcoumarins offer particularly excellent point for diverse chemical space products, thus staring more complex products. Herein, we report an efficient synthesis 3-phenylcoumarin bearing ...

We investigate the question of whether any d-colorable simplicial d-polytope can be octahedralized, i.e., subdivided to a d-dimensional geometric cross-polytopal complex. give positive answer in dimension 3, with additional property that octahedralization introduces no new vertices on boundary polytope.
