The crystalline sponge method updated
Crystalline sponges are porous metal complexes that can absorb and orient common organic molecules in their pores and make them observable by conventional X-ray structure analysis (crystalline sponge method). In this study, all of the steps in the crystalline sponge method, including sponge crystal preparation, pore-solvent exchange, guest soaking, data collection and crystallographic analysis,...
متن کاملFlexible Zirconium MOF as the Crystalline Sponge for Coordinative Alignment of Dicarboxylates.
Because of their permanent porosity and unparalleled structural diversities, flexible metal-organic frameworks (MOFs) are promising and highly desirable in host-guest chemistry. In this work, we employed a flexible Zr-MOF system, namely PCN-700 species, as the crystalline sponge for guest inclusion. A family of linear dicarboxylate ligands was adsorbed in the void space of PCN-700, which were s...
متن کاملApplication of the Crystalline Sponge Method to Revise the Structure of the Phenalenone Fuliginone.
The structure of fuliginone was revised from a phenyl substituted phenalenone to a hydroxyl substituted phenalenone as a result of its re-purification via HPLC with subsequent NMR analysis together with an independent synthesis and analysis of the crystal structure, which was secured via the crystalline sponge method. On-flow High Performance Liquid Chromatography coupled to Nuclear Magnetic Re...
متن کاملCycloelatanene A and B: absolute configuration determination and structural revision by the crystalline sponge method.
Cycloelatanene A and B are marine natural products first reported a few years ago. Their relative structures had been elucidated by an extensive NMR study and found to be epimers. However, their absolute configurations had not been established because they were isolated in only minute quantities as oily compounds. In this study, the complete structures of cycloelatanene A and B, including absol...
متن کاملAbsolute structure determination of compounds with axial and planar chirality using the crystalline sponge method.
The absolute stereochemistry of compounds with axial and planar chirality is successfully determined by the crystalline sponge method without crystallization or derivatization of the compounds. This method is applied to absolute structure determination in the asymmetric synthesis of unique compounds with axial and planar chirality.
