Preparation and characterization of a new chiral metal-organic framework with spiranes

Herein we report the first homochiral IRMOF structure with chiral carbocyclic spirolinkers, basic Zn-(R)-spiro[3.3]heptane-2,6-dicarboxylate, named WIG-5. First, (R)-spiro[3.3]heptane-2,6-dicarboxylic acid was prepared involving a HPLC separation on chiral stationary phase, then further transformed into homochiral WIG-5 by the solvothermal reaction with zinc nitrate hexahydrate in dimethyl formamide (DMF). WIG-5 crystallizes in the P212121 space group and is built of two interpenetrated networks with pcu underlying network topology. The tetranuclear secondary building units (SBUs) of WIG-5 are coordinated to two DMF molecules and six (R)-spiro[3.3]heptane-2,6-dicarboxylic acid linkers, that results in the formation of a homochiral distorted MOF-5-like structure. Extensive characterization by single crystal X-ray diffraction, powder X-ray diffraction, polarized light microscopy, infrared microspectroscopy, solid-state vibrational circular dichroism spectroscopy and thermogravimetry/mass spectroscopy has been performed on the new material. Birefringence of large WIG-5 single crystals enables potential optical applications.

Fecht's acid revisited: A spirocyclic dicarboxylate for non-aromatic MOFs

Spiro[3.3]heptane-2,6-dicarboxylic acid (Fecht's acid, H2SHDC) is examined as a non-aromatic terephthalic acid isostere for the first time. The rigid spirocyclic backbone provides greater steric bulk than conventional aromatic dicarboxylates with consequences for pore chemistry and control of interpenetration, presented here in the structures of two new MOFs. Complex 1 is a three-dimensional rod packed structure consisting of Yb-carboxylate chains bridged by SHDC linkers which, although non-porous, exhibits a surprisingly high thermal stability for a spirocyclic cyclobutane derivative. Complex 2 is a co-ligand complex of SHDC with trans-1,2-bis(4-pyridyl)ethene (bpe) which contains linear solvent channels despite fourfold interpenetration. Although the framework does not retain its structure following evacuation, a clear difference is observed in the extended structure compared to the structurally related terephthalate species. This observation suggests the non-aromatic backbone of Fecht's acid and other rigid aliphatic linkers may prove an effective means to disfavour deleterious close inter-framework contacts which prevail in interpenetrated aromatic MOFs.

Cyclobutane-derived diamines: Synthesis and molecular structure

Cyclobutane diamines (i.e., cis- and trans-1,3-diaminocyclobutane, 6-amino-3-azaspiro[3.3]heptane, and 3,6-diaminospiro[3.3]heptane) are considered as promising sterically constrained diamine building blocks for drug discovery. An approach to the syntheses of their Boc-monoprotected derivatives has been developed aimed at the preparation of multigram amounts of the compounds. These novel synthetic schemes exploit classical malonate alkylation chemistry for the construction of cyclobutane rings. The conformational preferences of the cyclobutane diamine derivatives have been evaluated by X-ray diffraction and compared with the literature data on sterically constrained diamines, which are among the constituents of commercially available drugs.

Enantiopure spiro[3.3]heptane-2,6-dicarboxylic acid

Using chiral HPLC and 13C NMR analyses, the optical purity of (+)-spiro[3.3]heptane-2,6-dicarboxylic acid (1) obtained by the known diastereomer method with brucine was first clarified to be 90% e.e., which was conventionally considered to be 100% e.e. Among the ester derivatives synthesized, dicinnamyl spiro[3.3]heptane-2,6-dicarboxylate (2) was found to show high optical separation ability on the chiral HPLC with cellulose phenyl carbamate stationary phase eluting with hexane/2-propanol (10/1, v/v) at a flow rate of 0.4 ml/min at 35 °C (separation factor, α, 1.14), and the isolated optically pure (+)- and (-)-2 show [α]D26 of +1.84° (c = 1.74, CHCl3) and -1.84° (c = 1.74, CHCl3), respectively. Acidic hydrolysis of optically pure (+)-/(-)-2 without racemization yielded optically pure (+)-/(-)-1, exhibiting [φ]40527 = +21.1° ([φ]D27 = +9.1°) (c = 5.33, acetone) and [φ]40527 = -21.1° ([φ]D27 = -9.1°) (c = 5.32, acetone), respectively.
