AN ANTHRAQUINONE FROM HEDYOTIS DIFFUSA

A new anthraquinone, 2,3-dimethoxy-6-methylanthraquinone, has been isolated from Hedyotis diffusa.

Synthesis of six-membered functionalized carbocyclic compounds by one-pot reaction of hydroquinone derivatives and dienes

A general method for one-pot reaction of hydroquinone derivatives and dienes has been developed. The system of Pb3O4 in tetrahydrofuran- trifluoroacetic acid was found to play dual roles as oxidant for the generation of quinones in situ and as catalyst for the Diels-Alder cycloaddition, which makes the one-pot reaction efficient and easy to carry out. Using this method, a variety of six-membered functionalized carbocyclic compounds can be easily prepared in medium to excellent yields at room temperature. Copyright

Non-covalent allosteric regulation of capsule catalysis

Allosteric regulation is an essential biological process that allows enzymes to modulate their active site properties by binding a control molecule at the protein exterior. Here we show the first example of capsule catalysis in which activity is changed by exotopic binding. This study utilizes a simple Pd2L4 capsule that can partition substrates and external effectors with high fidelity. We also present a detailed, quantitative understanding of how effector interactions alter both substrate and transition state binding. Unlike other allosteric host systems, perturbations are not a consequence of large mechanical changes, rather subtle electronic effects resulting from weak, non-covalent binding to the exterior surface. This investigation paves the way to more sophisticated allosteric systems.

Synthesis of cage [4.4.2]propellanes and D3 -trishomocubanes bearing spiro linkage

Abstract: The synthesis of substituted cage [4.4.2]propellanes and D3-trishomocubanes bearing spiro linkage have been assembled with the aid of Diels–Alder reaction and ring-rearrangement as key steps. Here, readily available 1,4-hydroquinone, isoprene, spiro[2.4]hepta-4,6-diene and spiro[4.4]nona-1,3-diene were used as starting materials. The unusual rearrangement of cage propellanes with zinc/acetic acid produced D3-trishomocubanes in good yields. Graphical Abstract: Several cage [4.4.2]propellanes and D3-trishomocubanes have been assembled by Diels–Alder reaction (DA), [2+2] photocycloaddition, and acid-promoted rearrangement. Ring-rearrangement was observed in cage [4.4.2]propellane framework during the acid catalyzed reaction. Rearrangement approach provide new opportunities to construct unusual polycycles.[Figure not available: see fulltext.]
