New Synthesis and Structure Determination of 13-Aza-4,4,8,8,12,12-hexamethyl-2,6,10-trioxatricyclo[7,3>l?05’13]tridecane
The highly symmetric 13-aza-4,4,8,8,12,12-hexamethyl-2,6,10-trioxatricyclo[7,3,l,0513]tridecane is of general interest regarding several aspects. First, the molecule belongs to the rare point group C3. Second it is being discussed as a possible complexing agent [1]. Furthermore the title compound is quite inert against some drastic reaction con ditions, e.g. it does not react with lithium alu...

The title compound, C21H21NO5, crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the central 1,4-di-hydro-pyridine ring adopts a shallow sofa conformations (with the C atom bearing the phenol ring as the flap), whereas the pendant cyclo-hexene rings both have twisted-boat conformations. Each mol-ecule features an intra-molecular O-H⋯O hydrogen bond, which closes an S(8...

The six-membered oxacyclo-hexene ring of the title compound, C(13)H(14)N(2)O(2)S, is fused with the benzene ring and the quarternary C atom lies above the plane of the benzene ring by 0.229 (8) Å, whereas the methine C atom (which bears the acetyl substituent) lies below this plane by 0.595 (8) Å. The oxacyclo-hexene ring is also fused with the sofa-shaped 2,6-diaza-cyclo-hexa-none ring. The me...
متن کاملCrystal structure of the class D beta-lactamase OXA-10.
We report the crystal structure of a class D beta-lactamase, the broad spectrum enzyme OXA-10 from Pseudomonas aeruginosa at 2.0 A resolution. There are significant differences between the overall fold observed in this structure and those of the evolutionarily related class A and class C beta-lactamases. Furthermore, the structure suggests the unique, cation mediated formation of a homodimer. K...
