Org Lett. 2004 Mar 18;6(6):989-92. doi: 10.1021/ol049954a.

[reaction: see text] Synthesis of a chiral, strapped, cyclic bis(benzimidazole) ligand is reported. This compound forms a stable, Jahn-Teller-distorted, octahedral Cu(II) complex in which the elongated axis is positioned within the main macrocycle. The C(2)-symmetric bis(benzimidazole) core adopts a...

New algorithm for the Ising problem: partition function for finite lattice graphs.

PMID: 10991090
Phys Rev Lett. 2000 Jun 26;84(26):5924-7. doi: 10.1103/PhysRevLett.84.5924.

We present a new efficient method to find the Ising problem partition function for finite lattice graphs embeddable on an arbitrary orientable surface, with integral coupling constants bounded in the absolute value by a polynomial of the size of...

Lactide polymerization by well-defined calcium coordination complexes: comparisons with related magnesium and zinc chemistry.

Chemical communications (Cambridge, England)

PMID: 12610959
Chem Commun (Camb). 2003 Jan 07;(1):48-9. doi: 10.1039/b208679d.

Amide and alkoxide coordination complexes of calcium supported by beta-diiminato and bulky trispyrazolylborate complexes are reported together with their activity in lactide ring-opening polymerization; some are amongst the most active systems discovered to date.

Ruffling-induced chirality: synthesis, metalation, and optical resolution of highly nonplanar, cyclic, benzimidazole-based ligands.

Journal of the American Chemical Society

Fekner T, Gallucci J, Chan MK.
PMID: 14709088
J Am Chem Soc. 2004 Jan 14;126(1):223-36. doi: 10.1021/ja030196d.

Expedient five-step syntheses of a cyclic bis(benzimidazole)-based amide 5 and two sterically more hindered analogues 23-24 have been developed. These amides are chiral due to the inherent ruffling of the macrocyclic plane. Racemization of the optical antipodes of these...

Complexities in the ring-opening polymerization of lactide by chiral salen aluminum initiators.

The preparation of (R, R)- and (S, S)-salen Al(OR) complexes, where R = Et, CH2(i)Pr, CH2(t)Bu, and CH2CH(S)MeCl, are reported, along with their reactions with rac-lactide (salen = N, N'-bis(3,5-di-tert-butylsalicylidene)-1,2-cyclohexanediamino). Rapid, reversible coordination of LA to the salen metal...

Design, synthesis, and conformational dynamics of a gated molecular basket.

J Am Chem Soc. 2006 May 03;128(17):5887-94. doi: 10.1021/ja060534l.

We have developed a synthesis and examined the conformational behavior and recognition properties of dynamic molecular containers 1-3. As follows from the 1H NMR dilution, diffusion NMR, and vapor pressure osmometry measurements, compound 1 has a low affinity for...

Pseudomonas aeruginosa Chemotaxis Associated with Blooms of N(2)-Fixing Blue-Green Algae (Cyanobacteria).

Substituted cis-bicyclo[3.3.0]octenyllithium prepared by addition of t-BuLi to 3-methylene-1,4-cyclooctadiene in the presence of TMEDA crystallizes as a dimer with one unsolvated Li(+) sandwiched between the external faces of two allyl anions in a triple ion, and external to it...
