title: Concise and diversity-oriented synthesis of novel scaffolds embedded with privileged benzopyran motif.
abstract: A branching DOS strategy for an unbiased natural product-like library with embedded privileged benzopyran motif was established to provide complexity and diversity of resulting heterocycles with desired drug-likeness. The importance of skeletal diversity conducted on a privileged substructure was demonstrated through the biological evaluation of a small molecule library representing 22 unique core skeletons via in vitro cytotoxicity assay.
