The development of chiral architectures for chiral ligand and catalyst discovery is essential for asymmetric catalysis. Herein, we report the concise synthesis of a Si-centered spirocyclic skeleton, spirobiphenoxasilin-diol (SPOSiOL), and its derived chiral ligands. Using the chemical resolution method, the optical SPOSiOL could be obtained in high yield on a gram scale. Preliminary studies indicated that this ligand scaffold has great potential in transition metal-catalyzed asymmetric reactions. This finding further highlights that the Si-centered spirocyclic scaffolds are of great value in asymmetric catalysis. This journal is

On irradiation in methanol, the title compounds having chloro, trifluoromethyl or methyl group at the meta position on the styryl benzene ring gave 6-substituted (2) and 8-substituted (3) 1-methyl-3-(methylaminocarbonyl)isoquinolines along with 1-azetines
